Tatum and Louis all talk about the track developing after the first few follow the leader races so the material is purposely left to be flung to the outside of the tracks and graded in place rather than pulled about over the rest of the track. Once the inside is dead slick you can't pull the material down onto it. They need to grade the tracks more often than every 4 races to stop the build up but it seems that's what everyone wants, or is it? I remember the Huggy days at Lynn, grading with 2 tractors after every race ....
