np, good luck... id advise starting somewhere private.. backyard or something, you will fall.

another tip: until your used to clipping out, clip out the leg you plan to rest on about 15 feet before the actual stop, then when you get closer to the stop, put all your weight on the clipped in pedal, and turn the wheel away from your unclipped foot, and then finally put your foot down.

its really easy to fall when you first switch if your off balance
