There are a lot of guys in my city (it's a pretty rough city in general) that ride bikes because they have DUI's. I'm sure I get thrown into that category as well. I think if people actually watched me bike compared to the DUI guys they'd see some clear differences. Such as, I don't ride a bike that's been spray pained 15 times (a new color for each time one of the DUI riders stole it from another), I don't ride on the sidewalk, and I ride in a straight line.
