I'll have two weeks vacation in July this year, and I am planning to travel West starting in Cincinnati, OH. I'm riding a KLR, my wife a F650GS, she only has little to none off-road experience, so I'd like to stick mainly to tarmac, but the occasional hard packed dirt or gravel road should be fine. We'll travel light (e.g. hotel/motel for the nights). One thing I want to see is Mt. Rushmore, and my wife wants to see Montana. We don't want a preset route, since we'll ride until we get tired, and then continue the next day, so everything is pretty open. I think on average we should be able to do 300 miles per day, I know it sounds little, but I rather plan less then be disappointed. This brings about 4,500 miles round trip. Now my question, what are the "must see" points, and the "avoid sections" on a route thru Indiana, Illinois, Iowa, Nebraska, South Dakota, Wyoming, Montana, Idaho, Utah, Colorado, Kansas (I heard, I should avoid Kansas), Oklahoma, and Missouri? I know it's quite a laundry list of states, there might be some more to add.
