Sexist post! Only females can pee.
I piss anywhere I please (usually off my back deck (poop deck in nautical terminology
), note that I live in a wild forest. It is a territorial marker recognised and honoured by our fellow predators such as wolves and bears.
I do not usually crap outside because 1- it's hard on my knees 2- any place I don't walk is full of tall and prickly weeds, would have to get a machete and cut my way through (it's a second growth forest, so lots of underbrush).
In winter, when there is no running water I save the product and bury it in late spring when the ground thaws in a shallow trench dug where the weeds will grow in their time. It's called composting, supposedly completely digested by the earth in three weeks. This must be true, as I have the biggest and best and thickest and most varied green stuff I have seen in this area. Seems environmentally friendly to me.
N.B. The deposit must be covered with dirt, learn this from dogs & cats, otherwise our prey will notice and avoid the area, and a campground host will persecute you. I did that one winter in an NPS campground in Texas.
There is a true and funny screed called "How to shit in the woods"; google finds it.
