Tonight, Luke Bryan takes the stage in the grandstand.
Bryan is set to take the state at 8 p.m. while David Nail will also perform tonight. The pre-show features Shakin' Bake.
Bryan has made a name for himself in the country music world with such hits as "All My Friends Say", "Do I" and "Rain Is A Good Thing".
A good crowd is expected tonight, according to Mike Loher, fair board entertainment director. Earlier this week most of the track seats had already been sold out.
Loher said a lot of it will come down to how good the weather is tonight.
