I grew up in the Buffalo National River area, and it used to be quiet around there. Almost like the locals had a secret the rest of the world didn't know about...
Now, you can drive through Ponca or hike Lost Valley without tripping over tourists. You can't swim in the river without dodging kayaks every few minutes. Parking is a problem. Trash is a problem. Accidents and disrespect of the land are becoming huge problems.
It seems like there is a larger urge for people to get back to nature and make a connection lately.
I think our advance in technology is both driving this urge and forcing quiet communities and parks to have to deal with more tourists than ever before.

I really enjoyed hearing about your adventure! I'm sorry you had to deal with all the people. haha!
