I don't but I would in a second.
The sad part is that I live about 30 miles from where I work. If I leave real early, I can usually make it in about 45 door-to-door. However, if I leave at a normal time (anytime after 6:30) It takes me 2+ hours on average. Under nominal conditions, I could probably make the ride in about the time it takes me to fight traffic or take a train. Unfortunately, it's very difficult to ride into DC from where I live.
