We are looking to see the west; Yellowstone, Grand Canyon, Black Hills, etc. traveling by train from Chicago to AZ?. Looking for all comments. Should we rent a car in Arizona, drive north and say return from Colorado or vice versa? As we have traveled a bit though, don't know the western US at all, any and all suggestions are greatly appreciated. I have heard of a monument being built by the Indians, is it finished, where is it? Any other sights one should see?
Thanks in advance,
Chuck
