Northeast places to see racing shell seat installs in 3.2 Carrera or earlier 911s

[oly]

My goal is to see and try sitting in as many racing shell seat installations in 3.2 Carrera or earlier 911s as possible. I want to get ideas for which seat, bracket, and mounting option will work best for me. Does anybody have recommendations for places and events to go to?

I'm thinking Porsche Auto cross, DE, or maybe racing events at: Louden, Limerock, Watkins Glenn, or Mont Tremblant. Does anybody have any recommendations for specific events and dates at those places? Or maybe other recommendations?

BTW: I'm NOT looking for seat installation recommendations; I've read other threads on this subject an have all the information that I want.
