Where would be a good place for a "Man vs. Wild" type of adventure?

[Ron Burgundy]

For a long time, I've wanted to go out into the middle of nowhere with just a couple knives, some rope, water purification tablets, and maybe a few other things, for a week or so. Eat some snakes or monkeys or whatever, and make my own shelter.

Where would be a good place for this? I live in the Austin area, but wouldn't mind driving a long ways to somewhere. But I wouldn't go anywhere that has a lot of bears.

If I ever do it, I'll bring a camera and post lots of gruesome pics here.
