I was "forced onto the bike" last year. The clutch went out in my car, and I didn't want to sink the money into it. I rode for 6 months straight, averaging 4 days/week, until I got hit by a truck and entered the strange world of bike replacement. The looks I got from people were quite telling. When I was on my Gunnar and wearing bike clothes, I was looked at like a yuppie who was using the road as my own personal exercise track. When I was on my nerdy grocery bike, I was looked at like I had a DUI.
