You wouldn't happen to have a nice new bunker in the backyard?

I'd second dry meat, pasta and rice, and tinned foods. Don't forget plenty of water, you'll die of thirst before you die of hunger apparently. Not to mention that rice and pasta need it to be edible. Also the long life milk lasts for years.

How about sugared nuts? They are basically fat and sugar - full of energy. There must be places which sell them. Buy in bulk and save!
