Chamber pots, aka thunder mugs, are not as prevalent today, but I have one that's a family heirlom. (It possibly belonged to my grandmother.) In any case, my family used it when camping, in emergencies, and when I was camping on site when my house was being built--an experience you can read about in Building a Cool House for Hot Times without Scorching the Pocketbook. (We got started a little late--this was when the two-year rollover law was in effect--and we were advised that someone needed to live on the premises.) We had no plumbing, and one power line running to the temp pole, so we did have a fan at night.
