I like either Cape Cod, Ma or combining it with Carisle, Pa.  event.

If I am able to make that trip (depending on the time frame), I would vote for Ashville, NC.

It is about 1,750 miles one way from Rock Springs, WY.

Either July 15-16, or July 22-23, during either of the Pittsburgh Vintage Grand Prix race weekends.  July 15-16 is at the Pittsburgh International Race Complex - www.pittrace.com  Members could challenge each other on the Karting Track between the vintage races.  July 22-23 is in Schenley Park, where over 3000 cars are in a show on the golf course, while vintage racing is held on the streets in Schenley Park.  This is the 41st year of the PVGP, an all volunteer 10 day event benefiting 2 local charities.  https://pvgp.org/. 

Both locations has plenty of space for parking.

The PVGP has a 2023 70th Anniversary Z06 as a sweepstakes car - please visit https://pvgp.org/70th-anniversary-2023-corvette-z06-sweepstakes-to-benefit-our-charities/, and your donation could result in you driving away in a new, collectible, Corvette.

As a site selection,Clearwater beach Florida 

I do not live in the East Coast but would recommend when the event moves farther to the West to consider the Gilmore Car Museum in Hickory Corners, MI.  They have a variety of events throughout the year including Corvettes.  

Thanks to everyone that suggested a location!
