Story told to me 30 years ago: my friend Keith was at a bike race, watching the category 1 and 2 guys starting to line up for their event, when a cat 1 guy he knew came up to him.

Cat 1 guy: Keith, lend me your helmet.

Keith: where's yours?

Cat 1 guy: I rode 30 miles from home to here. Where was I supposed to put it?
