We probably don't really disagree about this that much. My BOB has the supplies you mentioned, as well as the "snares, etc" for more of a SHTF scenario. My important documents, insurance papers, etc, are already in a fire safe just in case I'm not at home to bug out. And I wasn't truthful when I said I had one and only one thing to grab. I would grab my one BOB... but I'd also grab my last-ditch, SHTF accessory: my H&K P7M8 9mm and ammo, with a list of all my neighbors who are unarmed and keep supplies.
My neighborhood is really a survival oasis: there is a liquor salesman with two rather plump children, and he doesn't believe in firearms! Talk about forage...
