Illinois pizza farm draws tourists. "R" Pizza Farm is "a half-acre circular plot divided up like the slices of a huge pizza. Each of the eight wedges represents something used on a pizza - from tomatoes to peppers to herbs including rosemary and sage. Three goats represent milk and Cleo the cow is symbolic of beef. Seven penned-in pigs illustrate pork." They do tours from April through October, teaching people about farming and organic growing, and wrap by serving pizza made mostly with ingredients from the farm.
