Multple headlamps, pocket sized flashlight and large/long Mag Light type flashlights that work on commonly available batteries. Also water purification (not just a filter), think General Ecology Deluxe and the best bottle type purifiers. Leatherman Wave tool or equivelant. Non-weapon weapons, i.e. Long Mag Light, oak/hickory walking cane, Spyderco Delica, pepper spray, as much for animal as people defense. Leather work gloves and Gortex lined leather boots. Bug repellent and headnet. N-95 masks with relief vales and nitrile gloves. Some diversions: a good book , I-pod, laptop, etc. Finally several tubes of Vicks to rub in/around her nose, because the stench of decay will be overwhelming. Good luck and God bless to your friend.
