We stopped in Kearney, Nebraska at the Great Platte River Road Archway Monument.
It is dedicated to showing the road west and has an interesting presentation using headphones as you move from area to area. They also allow you to boondock on the parking lot. We spend the night and were joined by several other units and a truck. It was hot and muggy and we should have run our generator and air conditioners like one of the other motorhomes did.
