I've never been to Dover Motor Speedway, much less watched the Haulers leave. It's quite a show. The trucks come down the backstretch and make a right turn up the banking and an immediate left while transitioning to a gravel surface. Its tight, has an elevation change, leans the tractor and trailer two directions and causes a bunch of wheel spin if the driver isn't 105% perfect.
BTW - Denny's hauler was still open in the garage by the time the rest left. Sorry.
