Ride a Bike!
Below is a video of Representative Patrick McHenry (R-NC) mocking the suggestion that bicycles may alleviate some dependance on foreign oil. I put over 4,000 miles on my bike last year, and not even a quarter that many on my car. I fill up with fuel every other month or so. The reason I can do this is because my city invested in a bicycle infrastructure (a few signs, bike lanes, tunnels, paths, and even a couple bike signals) that allow me to pedal to the store, work, school, etc.
Rep. McHenry - maybe a bike would also help you and your constituency shed a a few pounds?
