this isn't really SS- or fixed-specific... but most of the people who play messenger polo are on fixies so i thought someone here might be interested. My friend chase took a few pics and a little video at a recent polo match in seattle, I'll post the pics here in subsequent messages.

if you wanna watch the video see:

and

also, see http://www.axlesofevil.org/ for tons of pics and info for portland bike polo. i think there are teams in SF and other cities, not sure where to find info on them.
