About thirty years ago, I cycled everywhere. One day, in a rush to wrk, I slipped in behind a car, and flicked the back wheel over a patch of black ice. To make matters worse, I fell on my house keys which were in coat pocket. That bruise was something! At least I bounced back in those days. Now I'd probably break something....
Take care on your bike!
Still at least the dog likes going out and rolling in the eight inches we have had so far
