I'm planning a trip mid-August and was trying to pick a place to stay. Should I book a whole week at one place or leave it up in the air? We want to do Rushmore, the Badlands, the Dinosaur place, and bear country. It would be myself and my 8 year old son. Are all of these places where I can have a "base camp" or would it be better to stay in different places? I'm from MD and everything in our state is pretty close. Any help would be great thanks!
