I got a couple cheap, sturdy backpacks and have created His and Hers BOBs. They are largely redundant but some items are tailored to physique and/or ability. For instance, there are large work gloves in mine and small ones in hers. For fire, there's a mini Bic, lifeboat matches and a magnesium firestarter in mine. In hers, there's a mini Bic, lifeboat matches and a Storm Solo windproof/waterproof lighter. Mine has spare glasses. Hers doesn't need 'em. We could do well with one BOB, but the pair would make things more comfortable. Each contains roughly 30 items and weighs about 8-10 pounds. I wouldn't mind lightening things up a bit, but I feel like 32 oz. of clean water each and a couple Mainstay bars each will save time and improve morale in the midst of an urban evacuation, probably the most likely eventuality for me.
