Just throwing this old saying out there: "Two is one, one is none."
LONG LIVE THE SURVIVALIST!
well food wise i like to keep enough can and dry food to last three people for at least two months before i start restocking. my fridge is stocked with water and i too have a water purifier good for 12000 gallons. ammo wise i keep 1000 rds per gun(9mm & two assult riffles 7.62x39) the lowest i let the ammo drop is around 700 each before restock. mostly i tend to be more lenient on ammo than food
