This is actually one of the reasons I don't want to camp in the desert or where good water is a precious commodity. I also don't take a shower in a mere quart of water. Also, you can't get clean and you can't wash off all the dead skin cells in a baby wipe. Don't get me wrong, it helps...a little. It might make one FEEL better because it's cooling for a time, but it takes a real shower, more water than a few quarts, to wash off the dead skin and bacteria....but I digress.
I wash dishes in very hot water. It's one area of compromise I won't mess with. If I have to carry more water or go somewhere where I can get plenty of water, I'll do it. On the east coast, good water is plentiful and lots of free sources for it. There is no water shortage here.
And yes, paper plates are awesome! Someone on this thread said, just take care of the mess right after you make it. That's so wise. Organization makes this lifestyle do-able. It's how we can fit nicely into tiny spaces. If you have food rotting in pots and pans or sitting in the refrigerator, you're not making good use of space. For organization reasons alone, it makes sense to take care of dishes as soon as possible and put them into their designated spaces.
