Here is the game: You will be dropped off on an uninhabited island somewhere in the world. You can carry one item with you to help you survive and stay sane. What do you bring?
Rules:
-You must be able to carry it with you. So no airplanes or yachts. You can bring a canoe or inflatable raft if you want.
-Items come with accessories and loaded with their capacity of consumables, but nothing more. If you bring a radio, it is loaded with charged batteries. If you bring a rifle, it can have a scope and is loaded with a full magazine. If you bring a cooler, it's full of beer etc.
-You can assume the island will have fresh water, vegetation, and some animal life. Whether you can successfully live off these things is up to your skill and choice of item.
-You CANNOT assume your island will be somewhere a satellite phone will work. If you want to chance it and bring one as your item, good luck.
-You will be rescued in one year.
What do you bring? What is the outcome of your stay on the island? What did the guy above you bring that proves they're a complete moron and will certainly die?
