Well, having spent a lot of time under the stars and midnight sun, I can tell you it's nice to not have any radio, internet, television, traffic, screaming kids or industrial pollution when you are laying on your bed of spruce, head propped up on your pack, a wary dog curled up close, listening to the river and gazing at the stars or even the Northern Lights. Along with a good book, that's my entertainment. And it never gets old.
All I have ever taken is a radio (for weather reports and Mariner's games) and a tub of books. I have a CD player in the cabin.
I tie flies, make lures, tinker with my gear, shoot my .22 LR at a steel popper and throw the stick for the dog.
