I spent 7 of my 10 years in the USAF in England. Every year in the fall, they have "Grass Track Racing" out in the country. Take a mowed hay field put up some cones to mark the track, and have at it. A couple of heats of race Minis, then the Bangers would come out. occasionally someone would lose the steering and crash into a spectator's car. Great fun to watch, but just like at a hockey game, don't take your eyes off the action...
