Waah, you say. That's hard.Boiling pasta is hard? Heating up some refried beans and mixing in some cheese is hard? Ok, sure, its a bit more labor to slice up a flank steak, mix it in some chili powder and worchestershire sauce to dry it... but if you care about how much #@$%$ money it costs to buy freeze-dried food that costs a fortune for a mouthful, you will be singing the song of awesome once you start drying your own food. Buy a dehydrator. Cook some simple s**t that only needs to be reheated in boiling water (pastas, beans, soups, stews, etc), spread it on a tray, turn on the machine and 6 hours later, put it in a ziploc. Not only will you have SO. MUCH. MORE. food than you would have if you bought it from REI... but it will taste so much better. Plus, you can dry your own fruit and your own jerky (hence the skirt steak). And have a metric ton of it for a fraction of the price if you bought any of it.
Sure, you can always use this to store wet clothes... but did you know you could use it as a pack cover in the rain, or a makeshift poncho? In emergency situations, you can even dig a shallow trench, line it with this and collect rainwater.Oh, you can also use it for trash, I guess.
