Some people like "Topcat" from CA. just flew in in 07 and hung out. So did BabyElephant from Sweeden. No need to spend gobs of money. Find the cheapest way to get to Carlisle and hang out with Mopar people!
Driving 12 hours for me one-way by myself. Didn't see another Mopar fan headed the same direction, (that I could tell).
Kept driving because I knew there was a happy end point. Car people, a car show and swap meet. Same reason I was driving the Hot Rod Power Tour by myself, when no one else could go. Car people all enjoying a drive.
