It may be a terminology thing but anytime I hear someone ask about a bug-out-bag my first Q is "Where are you bugging to?" I don't have a BOB any longer. I have a 96 hour kit and various pieces of camping gear in my truck. My Camelback is part of that gear and would be the closest thing I have to a BOB. If things got out of hand here I'd just get in the truck and drive. None of this packing stuff on my back -- that's a non-starter.
