Yes, staying away from a water source is important. At least the bloke downstream won't be trying to filter the gunk and funk from me. I just wonder what's up stream. I have avoided soap of any kind but did buy a camp towell and cut it down a bit. Although I didn't even pull it out last trip. Next trip I will. And I'll pick up some camp suds at our local Outdoors store. They have a small size that would last me a long time. I carry a heavy black trash bag that doubles as a place to step out of my hammock to put on my boots, line the inside of my pack and be used to stand on when cleaning up. I thought of using my fly. (homemade Clark style made larger), as a screen for showering if privacy is an issue.
