*All ammunition is stored in brand new, hard plastic, water & air tight sealed ammo cans, with caliber painted on side of can

*All firearms are stored in a Fort Knox Legend safe, with the exception of the Barrett M82A1 which is stored in a hard plastic case along with its scope, and has all four padlock holes occupied with key operated pad locks

*I do not own any .40 S&W ammunition due to the fact that those firearms were purchased in the though of desperately scavenging for ammo, but I think I have enough back ups as to the side arm situation. My main side arm is the Glock 20, then the Glock 21, then the Glock 17.

In the garage, I have:

2 palates of toilet paper, heavily wrapped in plastic to avoid contamination
500 gallons of water in air tight containers that hold 4 gallons per container
Over 600 cans of fruit, veggies, beans, spam, and other foods, all used up by their expiration date and replaced immediately following their use
