I think I answered this same question on another thread. But if you are flexible and could consider South Riverside or san Diego County we have lot's of ranch land down here. The weather is certainly a lot nicer all year around and you can't beat the topography.
We've got Temecula Valley, Fallbrook, Bonsall, NE Escondido, NE Vista, Valley Center, Pauma Valley, Ramona and many other very choice ranchland in this area. Do you want to rent or purchase?
