Most of the suggestions so far have not just been West, but SOUTH West. I did see one person mention Idaho and having recently visited (but not knowing much and not able to really plan), it was very scenic. In particular, the road around Couer D’Alene lake was great and there is an old (but well maintained) switchback road taking you down (or up) into the valley that is Lewiston.

I would guess that looking a bit farther north might help keep us from the heat or at least open the dates up a bit

Yup, this! ^^^^^
Many members of all the sites also own C5s, so I'm sure will see them too. All generations are welcome. Non- Corvettes are welcome. We're just looking for members to be a part of the event no matter what they drive. Very often there are a handful of members there with metal cars. 

How about including us C2 owners too?

You are a member of C3VR.

It is a gathering of C3VR members.  Some don't even own a Corvette.

As a F.Y.I. to the above query,  we have in the past had a member who only had a C2 and was a creator and organizer of a eastern gathering in South Carolina. Did a fantastic job. We didn't go away hungry, and enjoyed many miles of roads and sites at his direction. A fantastic three days. Please consider attending. You won't ve sorry. 

It would be great to have it at an of those locations. Me and my 68 would be able make it to one of those locations. 

I am in Southwest Wyoming.  I would be interested in traveling to the Flagstaff/Sedona area, or even north of Flagstaff into southern Utah, in September-October.  I really do not know the area well enough to propose a good suggestion.

 I travelled from Phoenix thru Flagstaff a few years ago late November; but, November weather traveling north of Southern Utah can have travel issues with snowy roads.   I have some cousins in the Phoenix area I could plan to visit.

I'd love the West Coast gathering to be near Los Angeles, CA as that is where I live :) As for having other Corvette owners joining us, sure thing!

hi there, my name is Patrick and I live in Ohio. We have an annual event in Berea Ohio called Corvettes at Corsa every July. It’s a huge Corvette celebration at Corsa performance manufacturing. They were close to 250 Corvettes last year alone. C1 through C8s were represented. and I was fortunate enough to take second place in the C3 class. I think it would be a wonderful place to have the C3 registry at.😎

I'm with you Dan, but I don't think it'll fly...😁
