I found a TV show last night that was awesome. It's called Survivorman. You can also see more info and a blog here. I don't know how many sites it needs, but it is here also. Have you seen it? I guess this is the second season of the show. Basically, the guy goes into a wilderness area for 7 days and roughs it. He comes in with a few supplies, but that includes no food and water. He brings one match. Last night, although I was trying to get some work done, I got distracted and watched 3 episodes. He was Canada, the Amazon, and the Dessert.
If you haven't seen it, it is on Wednesday nights at 9pm eastern on the Science channel. Check it out!
