Hi everyone, I am planning on taking my 10-year old son on a 4 week camping trip. I was thinking of Yellowstone NP as our destination. Neither of us have ever been out west. Maybe stay a week in Yellowstone if that is not too long? We would also visit The Grand Tetons. Don't know if there is enough to do there for a few days camping? We would like to see Mt. Rushmore, if possible, and take a different route home than we went. Trying to make this fun for him so looking for things he will like along the way. I have visited many websites but would like some personal advise. Maybe see other National Parks along the way. Suggestions on ANY part of this trip will be greatly appreciated. I have already called Yellowstone and there are availabilities in the reservable campgrounds so need to figure this out soon. We will be going second half of July-August. Thanks again everyone.
