Thanks all. We're like 2 hours from Mt Rainier and they have done the Jr Rangers Program there. It was still an option last month when we went even with the buildings closed. The longest trip we have done was last Summer when the kids were 3 years old. We drove for about 8 hours into Oregon. They are actually pretty good about being in the car still. I think they entertain each other more than anything. Apart from the driving, all we do when we get places is activities/site seeing. That's quite the list around Rapid City. I'll look into adding those to the list. I'll make the reservations as soon as I have the schedule down. Hopefully this week.
