There's a natural spring just a short distance from here. Sometime about 30 years ago some kind of piping was added to it, so now the water comes out of a pipe a distance above the ground. People would fill their water cooler bottles there. About 10 years ago a sign was put up "This is not potable water". Now there are fewer people filling bottles, but it hasn't stopped everyone. I often bike past it, but I've never filled my biking water bottle. Like LinuxWalt, I don't trust mysterious water, even it does come out of a pipe.
