57 years ago, at 2 p.m. on May 18, 1969, the green flag waved for the first time to open Riverside Speedway. A 1/3-mile scale model of the original Bristol Speedway (TN), the track was built and operated by the late John 'Nova' Chisholm, also a racer - and father of our current owner, Donald Chisholm. Happy Birthday to Us! 🥳🎂🏁
