Arizona Rollcall.

Is there anywhere to get a few of us together to go pesting, squirrels, vermin etc?

I mean this in the kindest possible way.....you're going to have much better luck securing such an opportunity yourself. And THEN inviting some friends, once you've done the leg work and acquired permission to shoot pests on somebody's property. And if you have plans to bring friends the owner needs to be okay with additional people shooting there.
 
For any Arizona shooters not already aware....

Fun times. I don't ever regret getting involved in competitive airgun matches. Through the comps I met a bunch of really good people that share an interest in airguns, and most of them have become great friends.
