If I recall correctly Jefferson county also often has pretty high turnout.

There's some truth to what you said. But that doesn't explain why Denali is in the 40s. There's only one road in the whole park, and no private vehicles are allowed. You can get off the park bus and after it drives off you are completely by yourself in the wild. Not just any wilderness; it is majestic. The park is larger than Massachusetts.

Yeah, although I wouldn't think any national park would be remotely near trash. That said, Yellowstone can easily knock off a handful above it on this ranking. So is Denali.

Yellowstone is only ranked 51. I'll take this list with a huge grain of salt.

I wonder if any had video surveillance

Whidbey Island. It's bigger and you have more hikes, each of which is bigger in scale than those on Bainbridge: fort Casey, Ebbys landing, Deception pass.

That's not how they spelled it, not with English characters.

Swing north at Missoula to cover Glacier National Park as well if you have the time.
