Great advice in this thread. Especially regarding MREs. The fastest way to fuck yourself up on a number of fronts is to try to eat MREs long-term. They're expensive and have way too many calories.
One other bit of advice is that no matter what you land on for a food cache, the most important thing is to not tell anyone about it. Don't show it off. Don't mention it. You don't have shit. If you go around talking about it (even offhandedly) the best case scenario is that you'll have a friend knocking on your door begging. Worst case scenario is that it's not a friend, and they knock your door off the hinges. Starving people are desperate. Desperate people are dangerous. Especially if they're trying to keep children alive.
