Welcome 2 the board
, the best way to find hog hunts in your area is the internet, I have never Boar hunted in CA, but Texas, florida, and TN, TN being the best IMO, we were in the cumberland mountains central TN and man was that exciting, I shot a boar, then got charged by 2 at the same time!!! I jump to an atv and one runs by the other looked confused like I disappeared {although my buddy said they were just running from the shot, I felt like I was being chased}, so I gave him a 44-70 for good measure... What a time that was, when i got back to camp I found an open cut/scrape on the back of my calf and ripped pants, it was close, although I am not sure if it was from the animal or jumping on the atv, still fun...
I would start with the ca dept of fish and widlife, get all your licensing and all that bureaucracy out of the way, because I believe they are controlled their and if I am not mistaken most ca pig hunting is on private land, we looked into it once when were having a terrible first week of a 3 week Bear hunt in Oregon {weather, people, and woods in general}, but we ended up sticking it out and that turned into a good trip..
Anyway welcome to the forum, hope this helps you...
