I can shed some light on this.
I happened to be at the intersection of 182 and (?) the big road that goes by sanderson lake at about 9pm. At that time, traffic was flowing off campus very quickly due to four highway patrolmen manning that intersection. Traffic never backed up more than maybe a hundred yards. I saw Auburn's football team leave, along with their tractor trailer.
Shortly after that, all four HP left. I got in my car and when i got back to that intersection 10 minutes later, traffic appeared to be backed up all the way at least to the dorms. I guess they either
(1) got hungry
(2) had a report of a bad wreck somewhere that required those four specific HP cars, or
(3) left to go set up a DUI roadblock.
