Hey, wait, I weigh 260 lbs. . . . then again, I'm 6'3" and have lost 7 lbs. since going car free a month ago. . . congratulations! It's worth it just for the reduction in guilt about the oil war.
EDIT: Good luck on the IWs! I went through 30-40 IWs before getting a job I love. . . it sucks but you get good at it.
