The other day I was sitting at our lovely public library and for some reason typed "bicycle polo" into the search box, just to see what might come up. Much to my surprise a single entry flashed on the screen- "Unseen Cinema: early American avant-garde film 1894-1941".
Wha?! I rushed down to the A/V dept and, after a bit of digging by the clerk, rode home with a old dvd and the promise of black and white polo film.
It's old school alright. Don't mind the silly music and watch for the "trick shot" section around 1:40. A wreck gets cut off at 3:20, but luckily the ref (and his bum-bars) are there to see if he's alright. After some laying around and air in the tires it's back to to field... enjoy.
