Don't want to double post( I've already posted on the Mountain Bike forum), but this applies to more than one area.

One speed bikes, beer, and music. There's an interview with International Single Speed Association Founder (ISSA) Ronnie Pettit, a great article written by messenger Rebecca Reilly about fixed gear riding plus a bunch of other SS stuff. There's also a link to Hunter's interview w/ Pat Irwin on his Single Speed win of the Iditasport, so if you haven't already read it, do it now.
