Let me preface my comments by saying I get no compensation whatsoever from Harvest Hosts. I just want to share a resource that provides a terrific camping experience.
We just renewed our annual subscription to Harvest Hosts (I gave a membership to my DH for Father's Day last year) because we have had terrific camping experiences at wineries, here in California. Harvest Hosts has updated their website and on the home page they have a terrific video that explains the benefits of free camping with hosts at wineries, farms (how about an alpaca farm?) and other special places. With a nominal yearly fee you can camp for free on the grounds of some amazing places with some amazing hosts. As long as your camper is self-contained and you patronize your host you are good to go all over the U.S. www.HarvestHosts.com
