Once upon a time (many many years ago when we first moved out to the land) we had an outdoor shower. It was a long black pipe rigged up to a shower head that was heated passively by the sun. Very low tech. Surrounded by thick woods. It was actually quite nice. The stuff fond memories are made of. Of course, it wasn't quite so nice when the weather turned cold. And the view wasn't this spectacular either. But somehow we managed. We were young.
So yes, I've taken a wash on the wild side! Many many times. How many of you can say the same?
