People are enjoying the Tennessee Valley Fair every night. You see a lot of smiles, rides and food, but what you don't see is guns.

Chilhowee Park may be owned by the city but the fair has special rules.

"It's been our policy for over 15 years that no weapons are allowed on the fair grounds," said Sarah Carson, Director of Marketing for the Tennessee Valley Fair. "We are allowed to dictate what our policy is in terms of weapons."

The city of Knoxville classifies Chilhowee park as an "exposition center" that is why the fair can ban guns.

The Tennessee Valley Firearms Association says the fair is going too far.

"We don't think the city should be restricting us from carrying where the state says, "yes you can,"" said Liston Matthews, Tennessee Firearms Association member.

Knoxville police have metal detectors and will turn away anyone with a gun.
