I'll never go to Yellowstone because of this. I watched a video where there was literally a pack of what had to be 75-some odd tourists with service dogs and little kids making noise and guffawing as they all stalked a Bison at Yellowstone. It was sickening. National Forests are where it's at. Most of them have no amenities, so 80% of the visitors are hunters, fishers and people like me that care about the environment, leave-no-trace and don't want to see fat urbanites with service animals, clutching bags of McDonalds and toting bratty, noisy kids around.
