Hi, this is my first post. We are currently planning a 3 week road trip from ohio to the rockies. First headed to the badlands/rushmore and the like. Would like to see Glacier, Yellowstone, Tetons, perhaps Dinosaurs(or fossils at least). I've never been west of Chicago in a car. Suggestions/ideas would be greatly appreciated. We will be taking a total of 7 people. 3 kids and 2 seniors. Any insight would be greatly appreciated.
