We had a guy go in to hunt at Bear Island in Big Cypress in South Florida. He only went in 100 yards and could hear his buddies and trucks on Turner River Road. He fired shots with his rifle and his friends heard them and tried to find him. He was found 4 days later mumbling and near naked having lost all his gear. He was found in his underwear.
You can read it from the Southern airboat forums as it happened. http://www.southernairboat.com/phpBB...=22841&start=0

The blue trail is not even walkable. My SIL lost his shoe inside of 100' on that trail. I have a friend who got his Suzuki Samaria stuck for two weeks on that trail. My Dad won't go into Big Cypress because of a gator he almost stepped on on that trail. My best friend won't go there either.
