I just assumed I was misunderstanding as I wasn't corellating dish water to grey water. If its a sin then I'm guilty. When we go out with our little tent trailer we use a little was basin that doubles as our container for transporting our forks knives spoons and plates. Probably holds a half gallon of water. We heat a little water in our kettle on the Coleman stove or fire, pour it in the basin, wash our dishes and dump it on the road. Helps keep the dust down. :). I doubt this is what anyone is referring to as grey water in this thread. Oh, and yah, I pee in the bushes sometimes. :)
