I rarely see any other riders on my commute to work (at 11:30pm) but I do occasionaly see people on my way home. Almost always roadies with bad attitudes that don't seem to like a fat kid on a MTB with 2" wide tires passing them on a 2 mile uphill stretch. There is one guy that I see sometimes who is on a road bike loaded down with racks and bags and he always blows by everyone, even cars. He's gotta be like 70 and he looks like he's not even breaking a sweat doing it.
