When you think about an outhouse in an urban setting it doesn't seem to make a lot of sense. We have sewer servicing to our home, our bathrooms are warm and accessible. When Pam brought up the idea I kept going back to those two things forgetting some history and some practical reasons why this was worth considering.
To begin with, we live in the City but on a large treed lot. It's near the ocean and, many years ago, it was where my wife spent her summers at her Grandma's cabin. Outhouses in those days, especially in the "country" as it was then, where common and necessary. Pam grew up using outhouses and they seem to have a nostalgic ring for her. That's the history, the practical reason is that we pump our sewage up hill to the nearest main. When there is no power there is no pump and you have to think twice about using your warm, accessible toilet.
"I can hardly wait until summer and we have friends over for outside dinner parties, they can all use the outhouse!" Pam has lots of enthusiasm, I hope our friends feel the same way.
