Summer is approaching and the Knoxville Chamber of Commerce has been busy. And believe it or not, the Knoxville Nationals are approaching quickly. Melinda O’Field with the Chamber says there are many activities that the Chamber is assisting with, with one pressing matter being that there is a need for housing for visitors to the Nationals. O’Field also states that we have a balloon event over Lake Red Rock July 15-17, and Graffiti nights May 27th. Today the Chamber invites everyone to the Next Chapter Bookstore to their open house from 10-5, and the Chamber activity Business After Hours at the bookstore from 5pm to 7pm.
