out here the public toilet is an evaporating vault toilet, which is environmentally friendly. it's clean and smells better than most public restrooms and they keep it stocked with toilet paper, even though the rolls are locked to a steel bar so you can only use them in situ.
the thing that's hard to get used to, and especially when you first arrive in darkness, is the general quiet hum of the building and the breeze beneath you as you sit. i am not familiar with all of the particulars of the system, but it does involve a very gentle breeze.
it is so gentle a breeze that at first you wonder that it's there at all. but yes, it's a little breezy. it takes a littel getting used to.
