Another spectaculor fall day for biking so Vashon Island was the target. Cool start requiring light gloves but then it warmed up. While waiting at Southworth, there was some big and black in the water making a lot of splashing with a circle of sea gulls overhead and an eagle keeping watch. Could not figure out what it was. On to Vashon for a late breakfast sandwich that I could only eat half of. Just barely caught the ferry to Pt. Defiance where I did the 5 mile loop before meeting Dani, Jeromy and Nadine for lunch. Spent a lot of time over coffee and then heading home but found out I had no assist on a short but steep hill. Not a good sign.Got across the Narrows and pulled over to see what was wrong. Easy fix as the cable from the battery to the electric engine as loose. By the time I left Gig Harbor, my legs were telling me that 2 60 miles rides with a lot of hills in 3 days was expecting a lot. But I had a lot of battery left, so why not do some more hills on the way home. Data: I used the power assist often and whenever I needed it. Level 1,2 and 3. Still had 17% left
