Many Knoxville residents have taken a moment to catch their breath since RAGBRAI left. That break will be short-lived, however, as Southern Iowa Speedweek gets started with the 360 Nationals next Thursday at Knoxville Raceway. The Knoxville Chamber of Commerce reports that they’re looking for people willing to host guests for a portion of the week. They’re also accepting registration for the Craft and Vendor show. That will be in downtown Knoxville on August 10th.
