Just about a month ago.
1) Several guys in my club had fixies, and I jumped on the bandwagon too.
2) Converted Sanwa 700
3) Houghton, MI i.e. the very end of civilization
4) Because ridin' fixie through an annual total snowfall of about 200 inches is absolutely the best thing ever. And because people give me funny looks when I'm trackstanding and waiting for them to move their stupid ass car.
