Natural/organic meat directly from source in SD

I had a lot of discussions in the last several months about organic vs. natural vs. local regarding meat and produce. It is relatively easy to get local organic fruits and vegetables in San Diego at different places. But what about meat ? There are of course several shops which offer organic meat or natural meat, e.g. WholeFoods, TJ, Jimbos, Henrys etc. But at all thoses places it is very unlikely that you get local meat. So what are good sources in San Diego for local organic or natural meat ? And I am looking specifically for sources where I have the possibility to visit the farm and see how they raise their animals. (I don't want to go too much into detail about what organic means in terms of raising your animals but if you do some research you will find out that it doesn't have a big influence on the actual life of the animals). I just started some research on local places and was hoping somebody could point towards good starting points in San Diego.
