Summer trip. Needing ideas for family trip

Yellowstone!!!? Really? Summertime in Yellowstone is going to be overflowing with tourist. Don't get me wrong this country's National Parks are wonderful. We stayed at a campground in Thompson Falls Montana called Birdland Bay RV Park. It was wonderful. Not so much the campground, it had plenty of deer and wild geese and a beautiful beaver pond, and let's not forget the occasional black bear, but where it was located. Within an hour or so ride from the CG there were a ton of things to do and see. If visiting a National Park is what you wanted to do then Glacier National Park was less than 2 hrs away. Bike riding on the Hiawatha Bike trail. Visiting a giant cedar forest, kayaking on the Clarke Fork River. And if you are adventurous then you can go to a different part of the river for white water rafting. They have a list of about 12 things to see and do within about an hour from the CG. There is SO much to do and see without doing all the tourist stuff.
