Now Luann, don't be skittish. I've said it before, it is the law, you must fall at least two times with clipless pedals. One of those times should be at a stoplight, with a whole bunch of cars.

Seriously, what I did when I first started riding was clip in one foot, and keep the other out. That way, when I stopped I knew I wasn't going to fall. Once you get used to the feeling of slowing/stopping, you can start clipping in both feet.

Practice, practice, practice!
