My trailer was with my brothers car (showstopper with the orange 04 GT) it was parked at the farthest point to the rear right of the pits all the way in the back corner. On the return drive home, it sheared a lug off the trailer, on rt 101 not far from the track and upon further inspection by myself and a few others, it has been determined that someone was there removing 4 of the 5 lugnuts. the tire crossed the median and struck a semi, resulting in damage, although quite fortunate, considering someone could've been seriously injured, or worse. If you saw anyone back there with a hubcap off the trailer, or a wrench, i encourage you to come forward and tell me anything you know. not only could've my brothers family and any unlucky person could've been hurt, but this was my trailer, so not only did the person attack me, they attacked my whole family. Just the boldness and stupidity of the person or persons involved could have caused death, and this cannot be tolerated by me or any other track going individuals. thank you. Neil M.
