We're not neighbors unfortunately because we're spread out all over Southern California. By "enclave" I mean the area between West Hollywood and Arcadia, where many Eastern Europeans immigrated during the post-Soviet brain drain, not a dense conglomerate like San Gabriel.

BTW you do NOT want ten acres. That is a back breaking amount of work and even with modern technology you'll struggle to cope (it's not enough to afford most heavy equipment, but too much to do manually). You want an acre or two where you have enough space to plant trees. It takes a few years from nursery to fruiting, but they are far lower maintenance.
