For years, it just ran ... and people sometimes were lined up to fill containers with spring water, as it tasted excellent.
The State didn't like that, so they put up a big sign saying "This Water Has Not Been Tested and is NOT Safe to Drink! Drinking is PROHIBITED!"
Doesn't even slow people down. Every time you go by, there's someone with half-a-dozen empty plastic milk jugs, filling them up to take home.
I think it's like the notice that's on everything you buy here that says "This Product Is Known By The State Of California to Cause Cancer". And I mean everything.
What's happened is that the government has told us so much bullshyte over the years that no one pays any attention any more. It's certainly the way to bet!
