Some of the tracks I've looked at it's between $8 and $15.  I think it's also relative to the market you are in. Tracks in Dallas and the bigger Metropolitan areas can get away with charging $15 or $20 at the gate for certain events, because they are drawing from a potential market that is made up of millions of people.  In other words, even if they lose people's business because of the price there are many many more people in the area willing to make up for that loss.  In the Temple area, you are dealing with a much smaller demo, and you also have to keep in mind that a very large part of that demo is made up of military personnel, with a limited amount of disposable income.

Most of the tracks out here are $15 to get in the pits.  And not very many spectators that aren't part of a race crew.
