The last of the bean fields turned into retail a long time ago, and even the strawberry patches are gone. The Segerstroms kept their own estate as a farm for sentimental reasons, but that’s in Santa Ana. Costa Mesa has been definitively paved. Orange Coast College has a miniature farm for ag classes.
The Grange remains. I see AA groups coming out of there at night, but I have no idea if living or ghostly farmers meet.
