i'm getting off that island posthaste..
- inflatable raft
- tarp
water purifier first aid kit
- flare gun
reach the mainland, get rescued at sea, or bust
edit/ i talked this over with a friend..
they pointed out it said PURIFIER - nothing about DESALINIZATION
so.. i'd do a mini-still with the first aid kit instead
..i see some bottles, little bric-a-brac stuff i could use to set a screen and collect condensation
