Well if we're going to rough it (which looks highly unlikely :P) I will bring a water proof backpack. (1 thing.) In the backpack will be: a delta force survival knife, which has a compass and fishing gear in the sheath, a nice little liner lock pocket knife, a flask, ummm.... a first aid kit... more fishing gear (like sinkers and fishhooks and line, stuff like that), and... errrr.... rope, and instructions on how to make a bow and arrows.
Lol, is that cheating? I decided that I don't need to bring a laptop, just that stuff up there.
