Give me a break. When I was in the Boy Scouts, we cleaned the latrines
at summer camp every day with scrub brushes and pine soap. They were a
hell of a lot cleaner, odor-free, and hygenic than a lot of gas station
bathrooms I've been in. As long as they're not upstream of the water
supply, it's a non issue. Where do people think the wild animals in the
woods take a crap?

Here in Hawaii, the state has recommended (posted signs) that hikers not
swim in the pools at the bottom of the waterfalls on Oahu because of
bacteria from animal crap...
