Gallons Burned: 0.0
I just purchased a box of military surplus MREs (meals ready-to-eat) from my local army navy surplus store. Now I have 7 days of heated emergency rations in the event I get stuck in a blizzard/zombie invasion. I, being a total nerd for these sorts of things, did a little research and found out about the history of military foods stuffs from the Civil War forward. About 1.7 million became ill and 45,000 men died from tainted food in the Civil War. The Department of War (later "defense") has been working on this issue ever since.
Anyways the modern MREs I've got will still be edible for the next 7 years, so I'm all set.
For those who are interested here's the menu:
Here is the US government's official MRE site for further study:
