Well hells bells, when I was in the USMC many moons ago we called them AWOL (Absent Without Leave) bags....
I now use a Kelty back pack with a few items, including a basic load of: Ruger 5 1/2" SS MK II and three mags, 200 Rds Quick Shok ammo, Ontario 12" Bolo machette, Vict Workchamp, Streamlight LED AA Flashlight, Grundig Yachtboy AA Short Wave radio, two Motorola AA walki-talkies, lots of AA batteries, Cell phone, first aid kit, cross word puzzles, toiletries, baby wipes, two fleece blankets, lots of microwavable "cup" meals, Dintymore, Chef Boyardie, Hormel Chilie (these a great snacks and I don't even heat them).... water, and purifyer.
And if you don't mind, what does BTTT mean?
Thanks again,
OOF
