Smaller velodromes

I have long been interested in the small velodrome phenomena. The vandedrome was the first one that hit my radar. Then, a great regret in my velolife, I never bought the ticket to go to canada and ride the Human powered roller coaster.

I noted recently there is this tiny redbull branded minidrome floating around the antipodes:

Red Bull Minidrome from Radar Films on Vimeo.

Pretty neat, but maybe needs more banking, wouldn't it have been cooler if it was cross bred with this:

(put that on youtube!)

Or maybe crossed with a pump track somehow?

Welcome Coco's variety readers! Also, check your local paper for some more tiny velodrome action:
