AT&T U-verse in the SF Bay area lists a show called State Fair Foods on Travel Channel-West from 8-9 pm tonight (this is in the San Francisco area).

I'll record it on my dvr, but I don't think I can copy it onto anything else, otherwise I'd be glad to save you a copy (sorry!)

FWIW, the show description reads as follows:

Concessioners try to create the zaniest, most delicious, most carbohydrate-loaded and over-the-top edible concoctions; Maggot Melts and Belly Buster Burgers are featured in Colo.; ostrich, alligator and casserole on a stick are highlighted in Minn.

Nothing about Iowa, but that said, these episode descriptions are often wrong or incomplete.
