39F at 6AM today with patchy wet fog but I rode my Moto Grand Jubile to hopefully have a faster commute. About 1 mile out & on the darkest part of the commute, my headlight dimmed, then went out. I was just cresting a hill & didn't have much speed. While I was fiddling with the light (thought it might be a loose connection) I rode off the edge of the pavement onto grass & then went down when I tried to go back up over the pavement edge. Headlight was totally gone, & the butblinkies in each hip pocket went flying. Both went out as they hit the pavement! I felt some road rash & a very sore left shoulder but nothing seemed broken so I groped around & located my blinkies, got them operating again. As I got my bike up, I spotted the headlight of a fellow commuter approaching up the hill, he greeted me & we tried to ride on but my crank freewheeled & there was a ratchety noise coming from the rear wheel. We coasted down hill to a streetlight & found my chain off both front & rear sprockets. Doh! Got everything back in place & rode on to work. I am going to see the Doc this afternoon as the shoulder is really sore. It feel's odd & I don't have the range of movement that I ought to have. Serves me right for riding a bike without a backup headlight. Be careful out there folks. Don
