No, he dropped the bike very near a rattler though. We tossed sticks and sones at the snake from a distance but he didn't seem to care. He appeared to get bored after a while and slithered off. Then we could grab the bike and roll it a little ways down the trail before repairing the tube.

I've ridden over a black snake but she didn't get it in my spokes. A pigeon flew into my wheel once, and lost a lot of feathers, but I guess he bounced off or something. I rode over a squirrel, he looked OK somehow, ran off...

I hate it when stuff like that happens, although if one of those incidents had caused me to take a bad spill, I would have hated it even more.
