I found the Solar Living Center in Hopland, Ca, way back when I first started traveling. I described it as “The Whole Earth Catalog brought to life”. A large grounds with a store, solar panels, water treatment exhibits, and whatever it took to go back to the land.
Several years ago the store closed down. A licensed pot shop went in fairly soon after legalization. It was notable because one could partake on the grounds, a rarity in legal states. I was there last year just before the pandemic.
It couldn’t survive the pandemic and is now closed up. It was a living museum of the alternative culture that arose around here.
