I wonder how it smells? I shower often while deer hunting but regardless of the cold, I have never seemed to mind. We heat the water..and some cold to the mix and hoist it up. Creates a nice shower, me and a buddy can both shower with about 2 gallons..I could do it with less, but I've got it since I cart it in. In the summmer, we travel and use the creek.

Still...it's interesting thought.
