I have yet to attend one of the clinics, but I’ve heard mixed reviews. Most of the negative reports echo what you said here, that it’s not much value to someone with much experience. The folks who got the most out of it were the newer hunters.

Anyone else attended one of the pig hunting clinics? What did you think?

I attended the above clinic at FHL. I found it entertaining, but learned practically nothing about pig hunting. To say I was greatly disappointed after spending 2 hours traveling, each direction, plus the gas req’d, would be putting it mildly.
They skinned a pig on sight and that was educational, but as far as their statement “The clinic will cover the considerations and requirements for a successful wild pig hunt, techniques of locating the animals and different methods of take” was non-existent. I have learned more about pig hunting and techniques off this website than at the “Clinic”.
Too much time was spent talking about the use of “lead free” ammo and the protection of the California Buzzard, sorry, Condor.
The BBQ was great, although $10 was a little steep and the district Warden was great with his tales of game law violators.
Summary: if you have done any reading or actual pig hunting, I believe that this “Clinic” would probably be a waste of your day.
