A full 2 day supply of food.
Basic Hiking Gear including a pot/metal cup.
Good long distance 2 way radios.
flashlight with spare batteries.
Full psk with signalling devices.
Maybe even a flaregun? It may pose a fire hazard in forest tho.....I dunno about that one...Im sure if the guy in the worm eating thread had a flaregun he would have gotten noticed in the dark.
