Why? It's very informative. Us girls have to pee too, you know. We have been known to belch and fart too ( not me, obvs)

At Wood Festival they have straw urinals and composting "Squat n drop" toilets, you just throw a cupful of sawdust on your er...deposit, when you've finished...... ok they still pong a bit but nowhere near as much as those portaloo cabins....
we have a little old lady that still takes the bucket over the road every morning and chucks it down the valley ,although she has mains drains... you might need a septic tank ,sound`s expensive ,it is good when we have a flash flood and all the turds fly down the street.. welcome to France..
