KINGSPORT — Rain washed away last week’s plans at Kingsport Speedway, but it couldn’t dampen the enthusiasm for the season-opening Food City 175. On Saturday, five divisions in the NASCAR Whelen All-American Series are scheduled to be in action: the featured Late Model Stocks, Pure Street, Mod Street, Pure 4 and Mod 4 classes. Grandstands open at noon, followed by practice, qualifying and racing, which starts at 3 p.m. The three-eighths-mile concrete oval is known for its intense competition.
