I met these Mormon missionaries who took road bikes up the hills, town to town, through the 'hood. They were some hearty d00ds from Ohio, I think they may have even got here on those bikes. I kinda hope I run into them again, even though I don't plan on becoming a Mormon.
The only commuter I know personally is my brother... I was able to convince him our town was perfect for bikes and public transportation. So far, he's going along with it.
