Wall mod drivers running sportsman races  

I just read that Jimmy Blewett and Andrew Krause finished 1-2 in the most recent Wall sportsman feature.  I do recall that, in the past, Wall mod drivers have occasionally competed in sportsman races.  I'm not in favor of it but was wondering if any 3Widers out there can offer their opinion as to whether acceptable or not, and why its good for racing (the track, the drivers, the fans).  I not aware of any other tracks that allow the practice.  Not trying to create a controversy, just finding it an interesting topic for discussion.   Scott Ely
