  Hey Mike, Some info for your trip: Somewhere out west, maybe South Dakota, there is rumored to be a castle made entirely of corn. (I think it's really corn cobs, you know, not little tiny kernals. ) And also I know for an almost-fact that somewhere in Nebraska there is a site where they have reconstructed Stonehenge out of old cars. If I think of any other interesting examples of "Americana" you should see, I will let you know. AM
