Yellowstone is an odd and awkward combination of things.
I grew up in that part of the world and, unlike the author of the linked article (and the people he writes about), I spent a lot of my time in the outdoors. In fact, in the summer, my family spent more time traveling and camping than they did at home. I don't even remember learning about the outdoors - it's as if I've just always known how to function in it.
And from that point of view, there are two distinctive facts about Yellowstone.
First, as noted and as is obvious, it's packed full of tourists, most of whom know nothing at all about the outdoors.
The other thing though - the odd and awkward thing - is that it's unusually dangerous - not just to ignorant tourists, but to anyone. As a matter of fact, between the geysers, the terrain and the wildlife, I'm hard-pressed to think of another place in the whole of the northwest that's more immediately and inherently dangerous than Yellowstone. I mean - there are certainly places you can get to that are more dangerous - high in the mountains or deep in the deserts - but those all require significant effort. To just get out of a car and walk 50 feet into danger - nowhere else is even close to Yellowstone.
So it's just sort of ironic that it's also the place stuffed to the brim with dumb tourists.
