Law #1: Whichever direction you travel, the prevailing wind direction is a headwind.
Law #2: If the forecast calls for a chance of rain, that means there will be a steady, cold, driving rain any time you are on the bike. The sun will come out when you reach your destination.
Law #3: You won't notice the flat tire until you are already late leaving for work.
