Retired with apartment in Santa Barbara looking for friends and/or RV parking/permaculture space

Hello fellow Permies. We’ed enjoy spending daytimes in the garden and dabbling on things outside in a friendly place. We have a solarized RV with composting toilet I’m looking for parking space for to do permaculture, gardening, and community. We also have a apartment/condo in SB for nighttime living. The apartment has been rented out for years but we are moving back to SB in January, 2022. Ive done permaculture in Oregon and Washington and hope to in CA. We may search for land at some future time but for now we’ed like to chill out in the SB region. We’re mellow folks who have lived in Europe a lot. I’d like to start a network of friends in the SB region. Any suggestions?  I dabble about in off grid solar, native plants, permaculture plants, stove design, gardening, etc. I’m also open to bartering. Or simply making contacts and like-minded friends even without land or parking space to rent. Hello boomers. Thanks
