Although NASCAR Camping World Truck series has the weekend off, some drivers aren’t slowing down. Two of those drivers include SS Green Light Racing’s David Starr and John King, who spent a long day at Gresham Motorsports Park to prepare for their next race in Kentucky. John King of Kingsport, Tennessee joined Starr on the track at GMP to make adjustments to the truck to prepare for Kentucky. King is looking to finish the season strong in the Camping World Truck Series. [King made four series starts in 2010; Kentucky would be his first 2011 start.] (Gresham Motorsports Park PR)(6-29-2011)
