I wouldn't consider JOCCI "formal". Yes, it's formal in the sense that there are rules and club bylaws as well as a Board... but that doesn't affect the rest of the club other than it helps it function better. I've been a member for awhile now and we get together for food, drinks, shoot guns, wheel and camp. Not very "formal" at the actual events.
