Mechanical engineer, 36, Glenville, N.Y.
I bike or run to work. Biking is just as fast (there is a bottleneck bridge -- I don't know how cars can be so patient!), it saves me a boatload of money -- and my car lasts much longer.
It keeps me sane -- I get time to ponder, unwind from work, and relieve stress (due in part because I am losing my son to autism). And once a year I reward myself for the fitness gained by doing an Ironman triathlon.
I am not a natural athlete, and would otherwise tend to put on a lot of weight, but hitting the road constitutes a large chunk of the training I need to go long. WHAT FUN!
Between the above blessings of leaving the car at home, I would bike and run even if gas were free. How 'bout that, America!NEXT: Jessica Haberman: Gas bill up 24%
