While sprint car racing will be the main attraction as it always is at the Knoxville Raceway, other motorsports events dot the July calendar at the half mile to wet the pallet of any motorsports fan. This Tuesday is the annual Harris clash I-M-C-A Modifieds. The I-M-C-A Deery Brothers modifies and sport mods will race on July 26th. Also the Knoxville raceway will transform from a dirt oval to a pulling strip as the N-T-P-A brings its tour for a truck and tractor pull event on July 21st.
