Welcome, Koby!
Carlisle is always a lot of fun and not even because of the cars! My wife and I have been going for several years now because of the awesome people here at CC.C that we just can't see enough!
Some people trailer their cars to and from every day. (I never understood it much myself - they're CARS!) but certainly it's an option. We usually get there before 8am to wipe our cars down and get something to eat (there's a little outdoor cafe at the north end of the fairgrounds that makes a BIG breakfast for around $6 or so.)
On Saturday we'll be providing lunch as we have for several years now. I think we're doing italian sausage sandwiches with peppers and onions again. Also there will be the third-annual unveiling of the unnoficial "Cuda-Challenger.com Beer" - brewed by yours truly! Saturday night we have reservations for the club at Dodge City Restaurant in Harrisburg. My wife and I "sampled" the place a month-or-so again and the food was spectacular. On top of that, "Big Doug" - the owner - is a Mopar-owner himself!
As far as what to bring, we wouldn't survive without our cooler (some hotels will even fill it with ice for you in the mornings) and folding chairs! Also, LOTS of sunscreen (it was 114 degrees on Saturday last year!)
The tent is the greatest place to hang out, cool down, and chat with other CC.C members. We always have a great time, I usually get called lots of silly names by 4Cruizn, and, well, we wouldn't miss it for the world.
