You have to remember too that 7 of those years the Camaro wasn't even in production. So, of course, the participation has increased with the rebirth of the Camaro. I've witnessed it........ been attending Carlisle since 2006 with my 4th gen. The first year I took "Miss Thing" to Carlisle in 2010 the 5th gen participation was huge and the American Camaro Association was the host.
