SELINSGROVE, Pa. – Selinsgrove and Williams Grove Speedways have joined forces to offer the Hoseheads.com & Modern Heritage Back-To-Back-For-Jack 410 Sprint Car Bonus Challenges, at both speedways Aug. 28-29, in conjunction with each oval’s Jack Gunn Memorial races. So when fate found both Williams Grove and Selinsgrove Speedways planning to stage their annual Gunn Memorials on back to back nights, the races seemed to call for a little extra promotion. On Friday night, Williams Grove will host twin 20-lap mains paying $4,000 each in honor of Gunn while Saturday’s Selinsgrove show offers a 30-lap main paying $5,000 to the winner.
