Invitations were sent out this month for the Knoxville Chamber of Commerce’s Annual Volunteer Appreciation Dinner being held Saturday. That’s according to Jesse Wilson, executive office coordinator for the Knoxville Chamber of Commerce. She says the dinner will be held at Dyer-Hudson Hall, and will include tickets to the races Saturday evening, which is McKay Insurance Night. Wilson says the dinner is chance to say thank you to all the volunteers that helped during this year’s Knoxville Nationals.
