I have only ever shot at Tuckahoe (as far as I can remember anyhow) but from what I hear they are all ok clubs. Nathan and Don from Tuckahoe are "big wigs" in the federation and might have more information than that listed in the shoot book. Good Luck and Good Shooting.
Jefferson county is the closest.I don't belong to it but I know several of their memebers and they're all high quality,knowledgable guys.Joe Testi is actually a pretty good friend of mine.If I had more time,I'd actually get involved.
