Bob R, even if they never admitted the fallacious report, a bunch of us on this board have been savoring the Sierra water--unfiltered--for a long, long time. Over the years, you've helped us enjoy our drinks even more. I guess I'm bad, because I drank water out of rivers on the Sierra's west side right next to the National Park's dire water-warning signs (with, of course, no ill effects on me.) Thanks for letting us know about the proven fallaciousness after all these years.
As you well know, everyone has their sensitivities, and should drink accordingly.
