The Hot Rod Power Tour made a stop in Martinsville on Sunday, bringing thousands of cars to Martinsville Speedway for the first time in the tour’s 25-year history. The Hot Rod Power Tour, an annual event put on by Hot Rod Magazine, is considered the world’s largest travel¬ing car show, spanning 1,500 miles with more than 4,000 people participating the entire seven days of the tour. Thousands of people avoided the rain to see cars lined up along the infield and front stretch of The Paperclip, as well as many other classic, new and novelty cars and buses in the parking lots and grass hills of The Speedway. Martinsville was the first stop on the tour, which kicked off Saturday night in Concord, N.C., and will conclude Friday at Summit Motorsports Park in Norwalk, Ohio.
