Here it is the 2007 Cooper's Hill Cheese Rolling and Wake from Gloucester, UK. You can read more about it on this site. Even a few days of rain before the event didn't discourage the thousands who attended. This is an annual event where the object is to catch an 8lb Double Gloucester Cheese that has been rolled down an almost vertical hill. Can't be done of course, but I think the first one down the hill, living, gets the cheese.
