Hey BIG, if your up for a little site seeing and your going through Iowa, John Waynes birthplace is a neat little place to stop. They turned his home into a mini museum of memorabilia from his movies and personal life. its pretty small, doesnt take long to go through, but I thought it was worth the stop. IIRC, its about 15 minutes off of I-80.

Thanks D4L I will have to see what our plans are. I kind of like that sort of thing in Calif we went to the Richard Nixon and Ron Reagan museums and thought they were actually pretty interesting we got to listen to Mrs. Reagan speak she is one fine lady and person in my opinion.
