I have never been to Carlisle so it will be a learning experience for me to, but a friend who has been there 13 years in a row leads me to believe it won't be that complicated. I hope. I know that it is only $40 to park all three days in what they call the infield. I gather that's where folks park who might want to show off their cars and have them judged or rated by spectators. I also get the impression that whether or not you pay to park in the infield, unless you can leave your car parked overnight, it's first come, first served for next day parking. I plan on parking with a group of Mach 1 owners who are members of
mach1registry.org. The website does have a couple links if you want to check out some posts about the Carlisle? Here are some links.
