Around here, a number of houses really do have outside toilets - the shower, often; the commode, less commonly. But the bed and breakfast where my partner and I spent our second night on this island was configured that way.
And in deep-woods camping, it's common. Once at a Rainbow Gathering, which relies on trench latrines, I was hacking a new trench, naked but for the heavy shoes and gloves it takes to work a shovel - while the press of business drew other campers to the adjacent, nearly-full trench. People seemed to find the situation less embarrassing that glamorous, for its very oddity, and thanked me for my work.
Well, when I'm outside and need to go #1 I just hang it out and let it be! (thank God I'm a dude) when I'm outside and need to go #2, well, I just rush my ass inside and take care of business LoL. Other than that, can someone please let me know where are those outside bathrooms! I have yet to see a toilet in the middle of the woods/field ... LoL
The picture I posted is in the Boundary Waters Canoe Area in Minnisota (Near Ely). It's one of the two things that make a campsite on the US side legal. (The other being a fire grate). On the Canadian side, your lucky to get the fire grate.John AKA cobeachbum
