Todd,

Unless you want reserved seating, the way I would suggest is to buy adult admission at the gate, with the adult admission, it includes the pit pass, and there is seating in the stands for just general adult admission, it is a little farther down the track. If the link works to NHRA, you can see in the diagram that the gold sections in the stands are for adult admission, it is on a first come - first serve basis. If you are like me and most of the other people, you will be walking around the pits alot when they are working on the cars and only in the stands when they are running the Pro Class, unless you want to watch the Sportsman class's too. You can always find a place to sit, people will come and go all day. You don't need to buy one from a scalper, unless you want reserve seating like I said earlier. Fri is $32.00, Sat - $40.00, and Sun - $46.00 for the adult admission. Also by buying the tickets each day, if it rains you won't be out the money, in case you can't make it back for the rain date. The only bad thing is possibly standing in line each day to but tickets.
