Found out tonight, that riding on sidewalks is not necessarily safer than riding on the road. Granted it was night-time ... but I had my headlights and taillights on. I was ending one sidewalked-block and crossing a side road to get onto another sidewalked-block, and a kid turns his car right in front of me. I think the lesson to be learned is that car drivers assume that cyclists are just putzing along at 3 MPH when riding on a sidewalk ... and don't anticipate your gaining on their car if they turn in front of you.
So, that increases my average MPA to 70. That is to say, I'm averaging 70 miles per accident. Nurse, more coffee, STAT!
