One of my favorite tracks used to be the temporary circuit at the Olympia, WA airport - and not just because it was the site of my only "real" road racing class win (ie. where I beat people on the track).

There were no concessions so this wiener wagon guy used to set up in the paddock. It got so that I really looked forward to a beer-cooked meat tube smothered in 'kraut first thing in the morning on a race day...
