I belong to the Redwood Empire Chapter, for Sonoma/Napa county area. I joined a year ago and though I haven't attended many meetings, I've been to some of their fundraising sales at local farmer's markets, and to 2 scion exchanges. Really great people, fruit growing junkies like us all. Our scion exchange in Santa Rosa was awesome last January. In fact, one of my first posts on this forum, was to offer CdD Noir cuttings that I got at the exchange (of course mine failed). I went end of day, and still got cuttings of CdD Noir, St. Jean, Lampeira Branca, and many more. Members contribute from their trees and cuttings from Prusch Park were offered as well. It is truly unbelievable to see the scions offered for free. I got many pear, apple, persimmon... well, you get the idea, to graft to my trees. A beautiful bi-monthly magazine comes with membership too, just got the latest today. Membership costs very little, and I'd certainly recommend it to anyone in CA. Harvey C will chime in I'm sure, he's a long standing member.
