  1. There was a recently published study of Viking DNA ("the Viking Age, from about 750 C.E. to 1050 C.E., as well as some earlier and later samples.) from 40+ genomes and grave sites. Google 'Viking DNA' to read various summaries of the publication found recently in the prestigious journal 'Nature'. https://www.nature.com/articles/s41586-020-2688-8 The results suggest that the term Viking was likely more of a job description than an ethnic heredity. "The researchers write that this unexpected discovery suggests that complex settling, trading, and raiding networks during these times resulted in communities of mixed ancestry. Even more, the study's analysis shows that this mixed ancestry was taking place even before the so-called Viking Age, explains Martin Sikora, a lead author on the study and associate professor at the Centre for GeoGenetics, University of Copenhagen. https://www.inverse.com/science/viking-dna-study/amp "We found that Vikings weren't just Scandinavians in their genetic ancestry, as we analyzed genetic influences in their DNA from Southern Europe and Asia which has never been contemplated before," said Sikora. "Many Vikings have high levels of non-Scandinavian ancestry, both within and outside Scandinavia, which suggest ongoing gene flow across Europe." Quote: "They found that Vikings from what is now Sweden moved east to the Baltics, Poland, and the rivers of Russia and Ukraine, whereas Danes were more likely to head west to what is today England. Norwegians were most likely to set sail for the North Atlantic Ocean, colonizing Ireland, Iceland, and eventually Greenland (see map, above). “This is detail one couldn’t do based just on archaeology,” Willerslev says." "The genetic details may also rewrite popular perceptions of Vikings, including their looks: Viking Age Scandinavians were more likely to have black hair than people living there today. " https://www.sciencemag.org/news/2020/09/viking-was-job-description-not-matter-heredity-massive-ancient-dna-study-shows "Viking ships sailed forth from Scandinavia, traversing the waterways of Europe and reaching across the Atlantic Ocean. Vikings from different homelands preferred certain destinations; for example, men from Norway settled Greenland, DNA data now show." "Viking-style graves excavated on the United Kingdom’s Orkney islands contained individuals with no Scandinavian DNA, whereas some people buried in Scandinavia had Irish and Scottish parents. And several individuals in Norway were buried as Vikings, but their genes identified them as Saami, an Indigenous group genetically closer to East Asians and Siberians than to Europeans. “These identities aren’t genetic or ethnic, they’re social,” Jarman says. “To have backup for that from DNA is powerful.” I read about river trade routes from the Baltic sea to the Greeks (Varangians to the Greeks)...perhaps fitting the job description of ' Viking'... https://en.m.wikipedia.org/wiki/Trade_route_from_the_Varangians_to_the_Greeks#:~:text=The trade route from the Varangians to the Greeks was,and the Eastern Roman Empire.&text=Along the Dnieper%2C the route,its west coast to Constantinople. in the 8th to 11th centuries, some involving long portage's to connect between at least 2 specific rivers. "the Kunya River and possibly the Seryozha River [ru]. From there, a portage led to the Toropa River [ru] and downstream to the Western Dvina River. " They are mapped as shown below showing connections to Scandanavia. https://www.google.com/search?q=varangians+definition&oq=varangians&aqs=chrome.1.69i57j0l3j69i60.4359j0j7&client=ms-android-motorola-rev2&sourceid=chrome-mobile&ie=UTF-8 "Va·ran·gi·an /vəˈranjēən/ Learn to pronounce noun plural noun: Varangians any of the Scandinavian voyagers who traveled by land and up rivers into Russia in the 9th and 10th centuries AD, establishing the Rurik dynasty and gaining great influence in the Byzantine Empire." Although a bit off the topic of 'Viking' I once used Google Earth to create a map of a number of rivers and trade routes (including the Varangians to the Greeks) plus several major rivers in Russia, while rehabbing a sore shoulder following a few bad golf swings years ago. My KML/kmz for the Google Earth depiction of the rivers (and portage areas) can be downloaded (and displayed on Google Earth) from my Google Drive at the link Map plus terrain overlay: https://drive.google.com/file/d/0B07we0osMR1zMjdjY2FlOTktZjFkNy00M2FmLWFjOWEtOWU0MTdlZjFhNWVm/view?usp=drivesdk Map without overlay (more precise pin positioning to the rivers) https://drive.google.com/file/d/0B07we0osMR1zVkJwRmZwUExKZVE/view?usp=drivesdk "From the Western Dvina (aka. Duagava river), the ships went upstream along the Kasplya River and were portaged again to the Katyn River, a tributary of the Dnieper. " Note: the Kasplaya river is a left tributary of the Duagava river between (pink) pin positions #13 & #14 for the Duagava river pin set, at the town of Suraz.
  2. Normal glucose for me is under 140 which hasn't been seen since extensively riding a bicycle in January. I woke up a week ago and my blood sugar had faceplanted😉....a good thing for me. After ten years of diabetes treatment neglect my feet have some neuropathy and feel numbish sometimes (some days yes..other days no) after riding 10+ miles until I take a break.

  4. Assuming your shell to motor/wheel clearance is clear.....and that the pedal columns to shell mount area is not cracked (allowing shell to tire clearance to flex)... You might want to check that the large axle nuts , pressing the shims into position (at least on Monster and other Gotways) , are tight. Tightening the nut on the side where the motor wiring passes through the wheel will likely need a special 'channeled deep socket' tool which you might be able to create. Monster uses 24 mm axle nuts.
  5. I rode to the tip of Plum Island this afternoon. Lot's of cars (dust) and cyclists. A pilot flew some stunts overhead: https://photos.app.goo.gl/KUkqVwecFVuqFNvM7 I managed to find the aircraft/owner from a partial tail number search and an aircraft type (Extra) Id'd by Google lens. Here's the flight following of the (EA 300/L) EXTRA FLUGZEUGBAU GMBH.
  6. Night ride to Patton Park https://youtu.be/ACqzevjK2DQ Update: on the return ride, in the town of Beverly, I was doing about 10-15 mph in the bike lane when I was passed by another electric unicyclist using the middle of the mostly empty road. He was going about 25 or more mph. Not sure what type of euc it was but he shouted something as he passed....sounded really stoked..
  7. https://www.bbc.com/news/world-asia-china-53831271 BBC.com China record floods wet feet of Leshan Giant Buddha - BBC News I read that this has been a bad month for annual flooding in China. The Leshan Giant Buddha's feet even got wet. The restored Buddha is huge and carved out of the rock. My Monster mainboard that originally shipped before replacing the shell, a battery, pedals and motor has turned 20,000 km. Flooding in China was videoed by YouTubers in Chengdu, Chongqing. https://youtu.be/JEmEDbWxTzk https://youtu.be/WaYXAI16a2s https://youtu.be/A_PZb_3yGZI Wuhan is along the Yangtze river.
  8. @meepmeepmayerI got an email yesterday from the (5 unit) apartment owner. It has me a little nervous. No offense meant by my other comment.
  9. Sort of a humorous thought actually
  10. The motor / wheel / tire /axle is pretty much an independent unit and controlled by wiring from the mb passing through the small diameter axle. If the wheel doesn't spin freely then damage to (some place) it becomes the culprit. I can think of several (early ownership) crashes where the flailing Monster pedals wacked the street. That force transmits through the pedal hangers to the axle. I sold the first motor to a machinist who found it beyond his skill set to repair the axle motor. Good luck...hope this has helped😆
  11. Sounds a bit like my (old motor) Monster before replacing the motor due to a cracked axle. https://drive.google.com/file/d/1lKgFxj7LwOHDHvAeCe6hFGx1J6cFtWdX/view?usp=drivesdk
  12. So...last night (and very early this morning) I rode my Monster to a spot where I wondered if the Milky Way might by photographable in the midnight clear sky. @meepmeepmayerdoesn't like my night photos of where I shoot and it was close to pitch black (between the street lamps) on the Causeway to Marblehead so I'd not attempted to image the Monster after a fifteen minute ride from the apt. One time lapse picture looking across the ocean shows Saturn and Jupiter and the coastline but the Milky Way (to the right of Jupiter) was washed out in the light polution. One of several test images showed a meteor trail! Possibly a last meteor from the Perseids (ending Aug 24 @ 1 meteor per hour)? During that time a couple of girls traveled by on bicycles giggling about how they could hardly see and a man on foot, who switched to the opposite side of the road after spotting my camera atop the sea wall, were also out in the midnight light. I took the rail trail back to Salem on the Monster about 1 am. Monster has a good headlight and I wore a red LED head mounted light that I use while setting up the camera for photographing.
  13. The wear pattern on the right pedal of my Monster, after a few thousand miles of riding, Right pedal: shows that I use the balls of my feet to control the EUC in all aspects of riding. Loss of grip between the shoe and the pedal has not noticible , despite the wear, but my riding style tends to be conservative on generally smooth surfaces. Closer inspection of the pedal in the photo shows that the area is where the rubber of the sole of the shoe has deposited between the abrasive contact points on the pedal. The silver color is more a light reflectance when in reality the area is dark black. There is also a small spot under the left heel but not under the right heel. The installed pedals are the same age. The right pedal broke awhile ago and both pedals were replaced. Left pedal: Here is a picture of the left pedal , removed (and replaced) following the breakage of the right pedal. It shows the same wear marks under the ball of the foot and slightly under the heel as the installed L pedal.
  14. 😁🤓👍🇧🇷🎶🎵 I first listened to Indiara Sfair play harmonica on a Rolling Stones song (Miss you) performed by the group 'Milk n Blues'. She sounded great and the short dress fit well. From Curitiba, Brazil , I read that she is from a musical family. Some of her YouTube channel harmonica songs include: Blues, funky... really good listening.
  15. Humm... And about 9:55 -10:00 on https://youtu.be/EiFVPFANdDg
  16. Umm...uhh..YT of course! https://kuula.co/share/7M9qB?fs=1&vr=0&sd=1&thumbs=1&chromeless=0&logo=0
  17. Anyone else other than me watching Petra on her 'Crystal Rider' channel ?😋
  18. @meepmeepmayerSo....the quest for a meteor shot comes in part from ownership of the Photo Pills app which sent a email about the Perseid's Requesting the info from Photo Pills gave Making a plan with Photo Pills gives information on #meteors per hour, where to look in augmented reality and what your cameras field of view is at the choose location. The rest is showing up at a place where 2am loitering isn't an issue and pointing the camera at Perseus Photo Pills says..."shoot all night if you can"
  19. @meepmeepmayer"image reconstructed by some spy method or after the nuclear apocalypse." In the daytime it looks like
  20. Since I fumbled on using my intervalometer app I ended up manually counting to three between 20 second shots in search of Perseid meteors. At 2 am it is really quiet along the otherwise often used bike path. B&W looked better than the color with phone flash. I was relieved that I actually saw one meteor in my 180 shots taken over an hour. The site is a cleaned up 'lead mills' site along the harbor. "Reversing the environmental harm caused by past contamination is a challenge. Lead Mills, which is located along Lafayette Street (Route 114) at the Marblehead/Salem border, was an industrial site in the 18th and 19th century."
  21. One can either drive to the tip of Cape Cod at Provincetown (hours plus traffic) or take a ferry from Boston. The fast ferry (90 minutes each way @$94 round trip) really flies in a dual hulled boat. I went there by fast ferry a few years ago. When fully employed I used to drive there to watch whales (many finback) migrate out and over George's bank fishing grounds. https://www.bostonharborcruises.com/provincetown-ferry#schedule-and-rates Here is a video from a whale watch and from a walk to the tip of Provincetown. Finback whales !!!, Seals, Piping Plovers Map of Provincetown to Boston ferry route and car route. Timeframe is about 2005. Distance is about 60 miles not 92.8.
