For BOV you can fill a plastic 2-liter coke bottle with: cup of rice, cup of beans, cup of dehydrated veg, baggies with: AA batteries, pen light, meds, hard candy, cash, spices, suture kit, wrap the bottle with cord, bungee, gauze, use the empty bottle is a vessel, or fill with hot water for a warmer/heater, on and on... you get my drift. Actual bottle weighs nothing, waterproof, lots of stuff in it, its great. Give one to each family member to keep in their cars.
