I would bring plenty of water and food, I would also bring some thing to start fires with and some kind of shelter maybe. If I could I would also bring a female companion to possibly past
the time with. I think if I knew I was going to an island for any period of time, I would like to be as comfortable as I could be. Thats not to say a female companion would make me very comfortable , because they can make one very uncomfortable at times. I also think if I could I would bring something to signal a plain or a boat.
