Heidelberg Raceway sat in Scott Township, a few miles southwest of Pittsburgh, and ran from 1948 to 1973. NASCAR's top series stopped by four times, and the first stop mattered: on October 2, 1949, Lee Petty won the 100-mile Strictly Stock race there in a Plymouth, the first win of his career. The tour came back in 1951, 1959 and 1960, and Petty took the last one too. The track hung on as a local bullring until the early 1970s, when the oil crisis, sprawl and a lease nobody could agree on shut it down. The ground that gave Lee Petty his first win has a Walmart and a Lowe's on it now.
