I have just been to Nats in 2008 and it was great but I was told from vendors and car owners that Carlisle that i was way better organized compared to Nats. But leave it there for a month would be the way to go. It just gonna be some more flights.....! BUt it would be great to stay for a month. Both I have some family commitments too!
Don't leave your car bring it on! It is always up to the owner to do what he or she think is the best re their car. So bring her with you! If your car are the ones in your avatar they look really good. I like the old vintage dragrace style!
