Well, I understand that the Mother Earth types have designed some nice ones.
But the ones I’ve had to use were no piece of cake. Plus, they had spiders and maybe snakes in them.
All privies have spiders and snakes.
The best ones are in the far end of the shed, on the barn end, away from the main house. So you dont have to walk outside.
We had a privy at our summer cottage. My late husband, from Iowa, used to like sitting there in the summer. One year bees built their honeycombs on the underside of the seat board. If either of us had to sit, we were VERY nervous, especially in the late afternoon when the bees were all coming home. We were never stung. Perhaps they considered the smell of our deposits and ourselves as belonging to the hive???
