The wife and I are planning a fun drive to see Mt. Rushmore sometime in the late Summer 2010. We love to see silly offbeat things while on the road so if you have suggestions, we'd really appreciate it. BTW, we went on a roadtrip last summer to mid/lower Wisconsin and have seen all the wacky stuff between Chicago and Minnesota, so we're looking for a alternative route to take as well. Time isn't a factor so we can take a long route there.
