Here is the vid from the stoneboro pull a few weeks ago that was mentioned in another thread. Mat Cooper (NWPADMAX) won that night with a 503' hook. Notice is wipers are on the whole pull and the track is a "gravel" like material that when it got wet, the pan kind of hydroplaned. couple of other pullers went over 400', but Mat took it home...almost literally. Watch the tractor at the end of the track move out of his way and watch the flag man run trying to keep up. He had more in it, but the sled operator did NOT like being drug all over the place in that class, and blew the airhorns (can't really hear it on the video) and Mat knew he had it. Johnboy was there in Mat's corner that night, it was an awesome hook.
