Everything stated in the cycling rules above make sense except for the minimum wheel size. What if I really love to ride my BMX or foldable bike? I've ridden Henry Hudson Drive enough times to know how strange some of these rules seem to be. Anyways, I'm just glad to not be sick anymore. I've been off the bike for two whole days *gasp which feels like a long time to me. I did some short tempo intervals to ease myself back into pace the other day, and I'm glad to have my strength back. Cycling rules.
