I'd like to grow olive trees and press olive oil. It's a pretty good RE crop: very little maintenance and pretty lucrative. After the trees get going they are very hearty though I think it takes several years before you get any olives.

California is really getting into their olives. Some of the trees the Spanish Monks planted are still producing. I'm going to visit some farms in Sonoma this summer. I don't think you need a lot of land to have a decent crop. Now I just hope they'll grow in Santa Fe.
