O’Brien also noted that the number of students treated for alcohol-related problems and the abundance of hard alcohol at the kegless tailgates was frightening for the police at the game.

“We really feel caught,” O’Brien said. “Their job is to enforce the law and while you and I might not be that worried about a 19-year-old drinking a beer, that’s what their job is. We’re worried about other things.”

Gross said yesterday the planners for the Game had anticipated only 4,000 to 5,000 would come. While no final figures were immediately available yesterday, Gross estimated that between 10,000 and 15,000 were in attendance at the tailgate at Ohiri.

O’Brien said over 4,000 tickets were sold, many to alums who made the trip to Cambridge from all over the country. Undergrads at Harvard and Yale did not have to purchase tickets.
