My main concern will be potable water... I know there's plenty of water purification contraptions and tablets on the market, but I don't want to have to depend on anything that requires that I change a filter, or re-up on tabs.....I will have a small pot to cook in, is it sufficient to boil all of my water, or even drink directly from mountain streams if I have to? If boiling water is sufficient, I have no problem with boiling each night, and carrying a good amount of water on my person until I hit the next body or running stream of water... I will also hydrate a bit from the food that I eat as well
