FABO ROLL CALL Carlisle 2019

So, how does this work? When showing a car, I don't think I got a paper ticket. Last year I came by myself. Drove in and did not leave till late Saturday. Wondering if you leave for the night, and not in your show vehicle. Is it just on a hand stamp to get back in? Also you are supposed to get 2 admissions with showing car. What if other person does not ride in with you?
