Brit, thats a fantastic fun event you've got there! I've used two outhouses, not counting port-a-john's. One was the neighbor's outhouse when I was a kid. I'm not sure, was real young, but I think I remember there being two seats. Maybe a his and hers?. as a side note, I also remember the kitchen having a rock poking up thru the linoleom. And the other outhouse was at a not so pleasant stay in the cold weather at a girl scout camp. And I had those one piece nighties. That really sucked. It was cold!!!
