kentref gave you the fees for the Omaha metro area. I'd like to add to his that Iowa varsity sometimes does go to 75, depending on the school.

Mileage is a rare thing around here. Sometimes schools that have trouble getting officials will add mileage for 1 vehicle in addition to the game fee. There was one I noticed in Nebraska, but it's a 3 1/2 hour drive from Omaha.
