Muscle cars/Mopars at the strip is still about 95% Mopars. I think because it used to be Mopars at the strip for 10+ years, Chebby and Furd owners aren't really attracted to it.
What I like about it is that they have drag races and auto cross all weekend, next to all the vendors, swap meet and car show. Would I fly over from the Netherlands to go visit it?... no. But since I live 1.5 hours away, I go every year.
The Spring and Fall fling Mopar shows in Van Nuys - California are always nice to visit. They are completely different than the Vegas show. It's in Woodley park, so everything is on the grass, no drag race and auto cross and there is always a big swap meet. Bigger than in Vegas.
I've never been to Carlisle. Mainly because I'd have to go on a plane to get there because driving would take about 4 days. When we go to the meetings/shows in Vegas and Southern California, we usually drive there in a couple of Chis' Chargers.
