Ooh, that's a good one. Okay, assuming the word "things" excludes people, I guess I would take to an island without electricity:
1. Electricity - just kidding!
Okay:
1. lots of books
2. fishing nets
3. heavy duty skillet
4. a big knife
5. tent
I was thinking of Gilligan's Island, LOST, and the movie Castaway.
Okay, the next five: Name 5 movies with the word "love" in the title.
