> While the roads are clear, there are still a number of skateboarders who will go easily 5 miles across town. You know they do, when you get stuck in commute traffic and twenty minutes later arrive to see the same skateboarder you saw a long ways back.

I can attest to the validity of that scenario, only I've been in the opposite position: I commuted everywhere (school, work, shopping, home) on bicycle, and the rush hour traffic got so bad that all the cars were either crawling down the road or standing still ....while I whizzed by everyone in the bike lane.

The really excruciating irony is that I've done the same thing while cranking away on an uphill stretch of road.
