For the last year-and-a-half, I have been commuting on my 1990 Schwinn, "Jose Jalapeño". As of yesterday evening, I have updated my frame to a 2010 Specialized Allez Comp... I give you, "El Jalapeno Negro"!
Also, I've begun tracking my gas-free commuting on the little widget below. There's a small group of us here at the Boston/Burlington Nokia office that are doing so; my group seems to be 5th in the nation.
Edit: It doesn't look like my widget will post up here...
