YELLOWSTONE NATIONAL PARK!
It was the last leg of our 30th anniversary trip. You must take your kids! Yes, it's a long way from OK, but so cool and different than anything I've ever seen. My husband and I had neither one ever been here before, so how could we know? You have no excuse! The teacher in me says TAKE YOUR KIDS! It's a science lesson about volcanoes...and geysers and mud pots and other stinky, weird things. We loved it.
and mud pots
There's also awesome historic inn - that's me way up there!
Coolest log cabin ever...
