This was my first unclipping experience, in a parking lot with no cars in it.

1. slow my roll
2. unclip right foot
3. lean to left foot
4. fall

I am right handed and right footed, so I thought this was the logical thing to do. seems though, that my body prefers that right leg be ready to give me a push off and wanted the left foot to go to the pavement. Never would have thought about it beforehand. My LBS guy says always stop with the same foot, and now I do - my left foot goes down. I too wish it were the right sometimes, to take advantage of curbs, but it is what it is and I'm not going to fight it.

BTW this was back in April when I first got my bike. It's second nature now.
