I've been posting and lurking here for two or three weeks, figure I'll make an introduction.
I'm a young married guy, in grad school here in VA and am about to start bike-commuting to save $$$.
Stopped by to learn about what type of bike to buy, how to drive in traffic, etc. It's been very helpful.
No bike yet, but I'm saving up. Looking at a Scott Sub 20 or 30 (Sub 20 is on sale at the LBS, but by the time I buy it'll probably be sold.)
Noteworthy: I have a friend who once rode over 90 miles at an avg. speed of 23.8 mph.
