A little about myself, I am retired from the USAF and currently work for the State of Nebraska as a IT Analyst. While I was in the Air Force I spent most of my years overseas England, Korea, Panama (with many temporary duty assignments to places like Japan, Phillipines, Diego Garcia, Suriname, Japan, etc). I know a little about uninhabited tropical islands especially after my assignment to Panama. There are many uninhabited islands right off the coast of varying sizes as well as quite a few inhabitated only by the native Kunan Indians and we would often boat to these (off both the Atlantic and Pacific coasts of Panama). We would arrive with nothing more then a tent, water, first aid kit, diving gear (I am also a certified diver), fishing gear, and foodstuffs and spend a few days diving and fishing. Obviously I have never been to Niko but I do believe that one unihabited tropical island would have much in common with another and am very cognizant of what would it takes to survive on one of these isles as well as some of the hazards that prevail.
