Well actually, I ( @kennyskitchen here, I wrote this article) lived in Portland for over a decade before I started traveling.

As for the folks in Denver, everybody pretty much drinks either Manitou water, El Dorado Springs water, Uncle Charlie's water, or RO :-)

Getting people to care about what they're putting in their body to begin with is the key. Cultivating the awareness of how it affects your life experience, the simple fact that we have so much control of our realities, and practicing the self-love to actually choose to make it better. As long as folks are apathetic, disempowered, and disconnected, it doesn't matter if they have the knowledge or not.
