I think Tom is referring to crossbullranch.com in Topanga Canyon. I haven't been there yet but they could be a good resource. If you don't mind disclosing Mischa what farm do you work on in Malibu? I live in the Ventura County area and I am always in Malibu especially in the summer due to one my favorite little beach breaks, Zuma! I have been trying to find a good place to volunteer/gain experience with permaculture. If you guys have any volunteer days, need an extra hand on the farm, or even have other projects I am trying to break through myself and maybe we could get in contact. Good luck!
