Actually not many. The land near me is all new orchards, not really producing yet. Most of H & D's stuff is imported.
And in Lake County Ca they are pulling out the pear orchards and planting grapes. Thgey are allso pulling their walnut trees.
BTW...I live in Eureka Ca and the Times-Standard has many local stories of interest along these lines because a lot of this stuff starts here. I'm going to have to master that HTML and post.
