Well duh, However, I am betting it is not just gas prices. What do you want to bet that there are some other influences:
1. Lance Armstrong wins the Tour de France a record seven times. Against all odds. Interest in his success is at a fever pitch and highly promoted at the Discovery Channel to go biking.
2. The President has sparked new interest as the nation's cyclist in chief and called the most fit President in modern history.
3. Blog favorite Charles Johnson on www.littlegreenfootballs documents his rides and inspires (at least this) poster.
