HUTCHINSON, Kan. (AP) -- The Kansas State Fair is entering its final weekend.

Country star Billy Currington will take the stage Saturday night for the final grandstand musical performance. And Sunday's grandstand entertainment is a truck and tractor pull.

Weekend fairgoers also will be treated to an exotic animal petting zoo, milking demonstrations, pig races, horse shows, a chainsaw woodcarver and juggling performances.

This year saw admission prices increase for the first time in four years, with a regular adult ticket going from $8 to $10. Fair officials have said expenses have increased.
