550 cord is one of the best things to come out of Unca' Sugars brainy boys. you can use it to rig up all sorts of doohickys, not to mention lace up truck bed doors, strap down items when needed.
www.google.com and search for Bug out bags?
have you checked out equipped.com?
I remember someone posting up the yazoo about building a BOB and then always buggin folks to look over his contents list to see if he missed anything. Then it came out that he lacked basic land nav skills and other basic tenets of outdoors skills - also he admitted to not being able to carry his BOB. To give you an idea of what he had, he had spare changes of clothes including TWO pairs of levis, 6 cans of campbells soup, wool jacket, a 12" frying pan... among other things
do you have a small personal kit? Cause what good will a BOB do you if you get separated from it?
AIII large will look as though you are wearing a parachute pack, the becker large I find wanting, but there are those who will swear that its the next best thing to sliced MRE bread. There are better options than these. IMO.
Enough of my rant - just think smart and survive!
