I've been riding to work for two years now. It's great blowing by stalled traffic, smiling at hot girls in their cars, feeling righteous, and having an endorphin buzz before and after work. With all the money I saved on fuel cost, I've funded my trip to the PNW again this summer . Try it. You'll love it, and wonder why you hadn't done it sooner. The only drawback is you're at the mercy of the weather. The wetter the better. Then when I ride I just feel machismo.
Arch- When in Amsterdam Central did you notice the bike parking lot? They eat french fries w/ mayo, and they're not obese.
