A few of us had this conversation during Sprintweek and carried it on at Knoxville. For the 50th, run 25 laps with and 25 laps without the wings. Don't matter which is first. Same car must be used. I believe that since the Nationals started out without the lids, they should run 25 of the 50 laps without. That'll seperate the men from the boys IMO.
