I spent 8 days on Isle Royale a couple weeks ago and had an absolutely amazing experience.  It really feels like a world away, and doing it solo made it even more real.  Without any real form of communication with the outside world, everything just seemed more simple, I took advantage of every minute of the day and it helped me realize what types of things are really important.  I think everybody should do a similar trip while they are young, it gives you real perspective and a real appreciation for nature and the natural resources we have at our finger tips.  In short: Shut off the TV. Get off the couch, go outside and explore!  The real entertainment is in your backyard, in the woods, on the river, the lake, the beach, in the desert, the mountains.   Go outside!
