Hey, congrats - did pretty well for your first crash.
I rode San Anselmo for several years there, and crashed on it an hour after I got it - on my way from the LBS! It was a really weird crash: in the middle of a wide, smooth, dry, empty residential street I just lost balance. However, I haven't had a single crash since then. So it seems San Anselmos want to crash once when they're new and never again after that - just to get it out of the way I suppose; it's a law of nature that every biker falls at some point, so might as well do it and be done with it for a while.
