For the past 4 summers, I have camphosted up the North Fork at an area that sits right on the river. The middle of the river is the border with Glacier National Park. It is a very busy place with having a boat launch as well (I deal with thousands of people over the course of my stay). It's along the North Fork of the Flathead River, so it's the Wild and Scenic River System. Great floating, and some of the best fly fishing anywhere.
There is no power, no internet, water is a hand pump, and I get limited cell service since I bought an external antenna system to hook up to my phone (it still only works in a few areas).
It is absolutely gorgeous up there though, and a different kind of pace in life. I'm getting to make a difference in the place for many years to come. The Forest Service and Fish, Wildlife & Parks actually work with me on many things, and that relationship that has been built comes into play on other things besides the campground and river.
