Well I don’t know the areas. I do know that there are the types I describe in the PNW in general. I’m a member of a forum on permaculture(organic gardening, commune style) and there are many convos about how we bath too much and a lot of members from the PNW. We have a few here too and we also get a nomadic group called the rainbow people that camps here and there around these parts. They travel the whole nation though. They dumpster dive or barter for food.
Yeah, the vast majority of those back-to-earthy-odors types are from West of the Cascades; we are east. Basically flyover country here in eastern WA and Oregon.
