The first ever Lake Red Rock Balloon Festival is being held on Friday, July 15 through Sunday, July 17. The Knoxville and Pella Chamber of Commerces are helping to put on the event. 22 hot air balloons will gather at the Lake Red Rock Visitor’s Center for the weekend. Aanna Hoch, Knoxville Chamber Director, says one of the most exciting events happening is the tethered glow at dusk on Saturday, in which the balloons will hang above the ground, lighting up the night sky. There will also be launches at 6pm Friday, 6am and 6pm Saturday, and 6am Sunday, as well as all sorts of family activities.
