I helped my parents run a camp ever since I was a toddler, (when I could speak properly, they let me handle incoming phone calls at first), then it was basic household job related stuff, (dusting and running a vaccum during pre-school and early grade school years, plus working as a "parking organizer", cleaning out tents of bugs and dust, and cleaning latrines, A.K.A. outdoor toilets).
Now, pretty well here in the hills nowadays, you don't see "outhouses", but you will see "portable toilets", "porta potties" or "honey wagons", mostly at construction sites.
Ever wonder why there are "No Smoking" signs posted on them?
No, it's not that they want it to "smell like a smokestack" or the chemicals used to clean it... methane gas
Yes, our "poop" produce amounts of methane gas and in a enclosed space, (even with the door open), it can build up and if you "light one up" in one of them, you're just asking for a trip to the ER.
I have heard of stories over the years of people ignoring the "No Smoking" signs and later ending up in the hospital.
So, think before you go to an outdoor toilet next time to "sit in peace" & "light one up".
