BLVD RULES & TIMES ??????????

Anybody know when the cutoff is to be able to drive down the BLVD to drop off tailgate items before the game?
At the last game I arrived at least 2 hours and 15 minutes before kickoff and some young security kid in a yellow slicker said I absolutely could not drive down the BLVD to drop off my stuff. I stated that I had always done this in the past, but he would not relent.
Does anybody really know? A friend said he called the athletic department and they said the cutoff was "two hours before kickoff", but then security was waving people off before the 2 hour deadline at the last game?
