We are all living in what is now a pretty distant past and recalling the glory days that drive us in our passion for these automobiles. As our numbers decline on this forum and people continue to get even more advanced in age as these yearly event photos demonstrate, this phenomenon will accelerate.
In watching the very real turmoil going on in the automotive industry these days, including the rapid and intense push for autonomous driving cars, climate change that is pushing EVs and fewer fuel burning power plants plus the business case emphasis on ride sharing, the deline in interest from the general public will just accelerate from here on accordingly. Interest in cars of the 40s is gone and interest in the 50"s cars is rapidly declining especially in terms of anyone wanting to take on a complete restoration anymore (because of the difficulty, parts availability and cost perspective). The cars of the 60s and 70s are up next. GM's best cars were designed and built in the 1961 - 1971 era IMO and that is probaby why the GM Carlisle meet is pretty much dead. Chrysler still had probably some of the best and most interesting cars over those years and well into the 70s, which probably explains why the Chrysler Carslisle event is still more alive.
All we can do is enjoy the interest that is left and the friendships that have formed and the good times such as events like Carlisle afford and accept the future for where it is surely going. Anything else is futile. I am OK with that and and am also glad I wasn't born any later given where I see people's values, mores and behavior going these days. I am thankful for the good run that I have had and glad that I won't be going all that much further, as I don't see anything in the homogenized, electronics based future to get really excited about.
