My plan is 3 months of food. Not sure what is 3 months of food is. I have maybe 50 cans of veggies 50 cans of meat stuff (typical soda can or so sized). I have about 50-70lbs of rice. 30lbs of dry beans. 20lbs of pancake mix add water only. Enough dry milk to make 20 gallons (3yr old daughter). 20 or so containers of bullion cube. 10lbs or so sugar. 2 boxes of salt. 15 lbs of oats. Spices. 8 gallons of bleach. A few container of vegetable oil. Only about 15 gallons of water though.
This is in addition to a completely stuffed kitchen shelves. Make sure you don't have too much dry foods. Water may be hard to come by. Make sure you have 2 or 3 55 gallon drums to collect rainwater or to fill up before a big storm or if rioters might screw up the water pumping stations. I am leaning on too much dry food. My items are 2-3 months old. I am looking into putting it in mylar bags. Another big thing I stress is food location. Put the stuff is waterproof boxes (I use heavy duty rubbermaid 20 gallon boxes). Also, don't store everything in 1 place in the house. If someone raids your house and finds it when they see 1 stash, they likely think they got it all. IF you need to evacuate quick those containers will make things mobile quick. Also, try to keep the dry food at 70 degrees or lower. Storing food in an attic is a bad idea. Don't forget your dog or cat.
I have about 20 gallon spare fuel and 5 cars I can pump dry. Have some sort of device to pump gas out of. Do not rely on anything electric in your home, even If you own a generator. Get a woodstove. Having a coal stove means you can also burn wood. People will steal firewood way before they even think of taking one lump of coal from you.
Not sure If you own a firearm. I have 3 military ammo can boxes full of ammo. One can has about 300 rounds of .30-30. The Other 2 cans have about 500 rounds of #6 20 gauge birdshot, 50 of #3 or 00 buckshot, 50 of rifled slugs, and 100 rounds of sabot style 20 gauge slug (they need to be used in a rifled slug barrel). I also have about 1500 rounds of 22lr. Might add another can a 44 mag or 22-250 for a new rifle purchase (lever action or bolt action varmit round).
Got some more in depth medical supplies like more large bandages, suture kit, iodine, and some more advanced life saving meds. My wife used to be a professional paramedic. Another big item to think of, can your area flood or be hit by a hurricane? If so the best lifesaving peice of equipment might be life jackets, good inflatable raft or rowboat (canoes are too dangerous in swift currents), and wetsuits. Add a good supply of rope and a lifeline.
