Ride your bike to work! I spend 1+ hours getting to work in the morning, and 1+ hours getting home in the afternoon, no matter what my mode of transit (bike, Metro, or car). I get some good reading and crossword puzzles in that time by Metro, nothing but alot of frustration and an aching back by car, and over 2 hours of bicycling every day when I go by bike.

Over 1000 miles and 90 hours commuting by bike since January. I'd hate to be spending the time in a car!

Now, before you say, "I can't do that. I have a fancy-clothed job, I have a small child, I have whatever," just think about ways that you can incorporate riding into your daily life. We'll give you specifics if you want them. Just tell us your obstacles and we'll provide some solutions. The best solution is in you, however. I changed my attitude from "I can't" to "how can I?". It has made all the difference.
