The A.D. final club closed its doors to undergraduates this week, puzzling members who say they were not given any warning about the closure, nor told why it would take place.

Members said they had received an e-mail message Tuesday from the club's undergraduate officers informing them that, effectively immediately, their keys would no longer open the building's Plympton St. entrance.

Also that day, hand-written signs appeared on the front door and window, saying, "Club is closed for renovations."

But the A.D. underwent a full makeover last summer in preparation for the 100th anniversary of its building, and members said the building appeared to them to be in fine shape.

"I think they're just fixing something inside," member Justin P. Finnegan '02 said. "It's a surprise to me, but I haven't been in the loop."

But other members, who spoke on the condition of anonymity, said the renovation excuse is merely a ruse to close the club to its undergraduate members until the end of the year.

"Last Saturday there were shenanigans going on at the club--some mud wrestling on the pong table," said a senior member.

According to three sources, club members had brought the table into the A.D.'s courtyard and mixed beer and dirt on its surface to stage personal wrestling contests.
