Had my first real spill this morning.
About 60 degrees with wet roads and an occasional drizzle; was feeling good about my pace. I made the silly mistake of trying to jump the metal threshold between the asphalt MUP and a wooden bridge. Lost control and stayed upright for a few yards; then went down on my left side on the bridge. A nearby family of pedestrians stopped to check on me, but I think all is well.
The impact took a good bite out of the left side of my helmet (behind my left ear) and broke my pager. Was stunned for a few minutes, but finished the ride; no obvious damage to the bike or my cargo (though I did have to straighten my handlebars).
This happens to have been the first morning I seriously considered wearing a baseball cap instead of the helmet in order to shield my glasses from the rain!!! Even had one lashed to the rack, just in case.
