"If you were stranded on a desert island what two items would you take with you, and why?"

If I were stranded on a desert island and only had the option of taking two items, I would take a solar powered vehicle, and a book about being stranded on a desert island. The solar powered vehicle was one of my first thoughts because it can become very useful in being able to be spotted by rescuers as well as come in handy when needed to search for survival items on the island. If worse comes to worse the vehicle will also keep me entertained while stranded on the island. The second item on my list would be a book on how o survive and get rescued when stranded on an Island. I feel it would probably be the most useful thing to have since knowledge doesn't run out I will be prepared in any situation.
