Awww, Bonnie, sorry about your fall!
It's true about people not knowing about clipless pedals. Once I tipped over as I was turning around to stop next to a friend. I couldn't get my foot out of the pedal in time, and over I went. We we out near a boat harbor at the time, and there was this guy camped there. I didn't realize he was there until I hear this roaring laughter and him commenting to someone in the trailer that he was laughing at some girl who just fell over on her bike. I just looked at him and said, "Hey, no making fun! I don't see you out here trying to ride your bike!" He continued to laugh and asked what I was doing. So I explained to him about the clipless thing and he said that he had no idea and now understood why I had tipped over. I think the guy was totally drunk--and it was only about 8 am!
Hope you're feeling better soon!
