I have thought about the Vintagers- I have two sisters living in NE Maryland and a early Fall visit might be fun. The Euro is a currency, like the French Franc and the British Pound Sterling- and Concentric barrel bores are a goal well worth achieving indeed. But I'm a Carhartt/Levi Strauss/Cabelas kind of dresser- can't see plus fours and a tie and weskit, so if you have to dress like that to shoot clays and drool over fine guns you can't afford, maybe not.
Glad the PGCA includes the Fox gruppen in the recent shoot mentioned. I'll be more than glad to bring one of my many 12 bore Smiths to a PGCA event anytime- those sweet old Elsies sure do shoot well for me--
