Yellowstone is too much. We were there for 3 weeks and I feel like I barely saw it. It’s huge, and has all the mountains and rivers and lakes and plains and rolling hills and water falls and animals. In addition to that, things are constantly blowing up. It’s too much to pay attention to. I have family who go every year, and I get that now. The Grand Tetons were nice too. I spent hours looking for a bison carcass that was supposedly being eaten by wolves, but by the time I found it, it was gone.
