I've taken the first step -- gotten some ATB shoes that are SPD compatible. Just the extra stiffness seems to have given my clipped arrangement a 1-2 MPH increase. But now I'm a little worried. Had a bike mechanic tell me this weekend that she once was ticketed for riding at night without reflectorized pedals. Well, clipless are usually un-reflectorized, and the reflectors they put on the "legal" clipless pedals tend to come off.

Anyone else have run-ins with the law over clip-less pedals?
