I remember at the Mopar Nats back about 2000 a 67 Plymouth b-boby was seen with a box in the car 1st round, came up for second round with the box in the car, someone had told the track about it. He denied using it, they sent him back to the pits to remove it, He missed 2nd round and came back up 3rd round without it and lost. A couple of NTR track guys came through the pits in 01 checking Pro cars for boxes, He said He was only 1/2 way through the Pro class and had found 12 boxes. Our 1st race this year, the Competition director at NTR followed us into the pit after 2nd time trial and went over every inch of our car. He did 2 others and never did it any more the rest of the year. Should spot check every week if you ask me.
