I admit that I have ridden my bike after having a few drinks. I NEVER ride if I suspect that I would be over the legal limit to drive a car. Exercise has also been proven to help sober you up, not that I count on that effect. When I have been drinking and I need to get home WITH my bike for whatever reason I will always take the longer safer way home using MUPs or sidwalks. Usually if I have been drinking then its at nigth so the sidewalks are empty anyways and I ride very slow and double check when crossing streets. Be safe out here!
