I did buy some from a guy a friend from the mountains told me about. Wild pigs, and here they are so difficult to catch and so prolific that you can shoot one per day. No artificial food fed to them, no ground up dead animals fed to them, no hormones, etc.
I loved the meat I got from this source, but wouldn't trust anyone else. I don't buy it much from the grocery store even, maybe once a year or so.
