Seriously, what did the article have to say? I cannot remember my login for DRF and i can't really be bothered to try and find it at this time of night here. I am interested to see what they are planning on changing. With the severe winters they can get at Turfway, and from seeing snow and ice affect the Poly over here once or twice, i think they have the worst problems with the surface.
After speaking to a few "regulars" at Turfway, they seemed to suggest that not enough work was being done on the surface during racing. In which case, it isn't really surprising that the surface was balling up so much. If it was harrowed after each race the surface wouldn't really have chance to settle, and therefore reduce freezing/balling up to a minimum.
