When I was 16, my parents and I did 7,000 miles in three weeks.
We left from Indiana and hit South Dakota, Wyoming, Montana, Idaho, Oregon, Washington, up to British Columbia, and then back down through Montana, North Dakota, Minnesota, Wisconsin, etc.
We had a pop-up and I was able to drive, giving us three drivers. We had a Chevy van with both rear bench seats removed, making a nice bed on the floor (this was apparently when parents didn't care about everyone being belted in), so we were able to take turns sleeping while driving and drive through the night.
Believe it or not, we saw a lot of stuff on that trip. A lot of the driving time was across the boring parts of Illinois, Iowa, Nebraska, Wyoming, Idaho, Washington, etc., so we managed to hit all of the major points of interest.
I know that sounds terrible to a lot of you, but it is one of the best memories I have of the time I spent travelling with my parents. We had a lot of fun on that trip (and others like it) and that experience is what made me want to expose my own son to fun family trips.
