[concours] JCNA Concours?

Dear All,
Pardon me as I’m a real novice when it comes to Concours-type shows, but I was
curious which Jaguar Concours is considered the best or “Grandaddy” of them
all. I seem to recall last year it was the JCNA concours at Stratton Mtn.,
Vermont. Will that be the case this year, and when is it?
Thank you very much!
