I believe the community/co-op pheasant hunting options have mostly dried up with the disappearance of wild pheasants and a drop of interest in pheasant hunting. There are only two left that I know of in Northern California -- Knights Landing Sportsman's Club --
http://www.klscpheasants.com -- and the Willows Pheasant Association (not Williams) --
http://www.willowspheasant.org --, which is run as a fundraiser for Santa Monica Catholic church. There used to be two in Willlows, but now just one and WPA acquired access to the former's property.
If there are any others out there, they are doing their best to keep them a local secret.
