When the A.D. changed its policy to bannon-members, Owl President Andrew D. Duffell '99said neither his graduate board president nor theundergraduate members were interested in followingsuit.

But one week late, the Owl implemented a trialchange and has since extended the ban on guestsindefinitely.

"It's probably easier for it to happen once oneclub did it. It's direction all the clubs havebeen moving in," Owl member Ryan G. Schaffer '00says.

And the other clubs' recent moves have proventhe response may not end until all of the clubsalter their policies.

Owl member Powers says the changes wereinevitable and have been in the works for over ayear.

"Eventually all clubs may be pressured intodoing it. They don't want to be left out in thecold," he says.

Heller agrees that the clubs that have upheldtheir current policies will ultimately change.

Without the A.D., Owl and Phoenix as socialalternatives, the other clubs will have to handlemore students than ever before. Even if the clubsare able to deal with their usual crowds, theextra influx could prove disastrous, Heller says.

"For some [clubs,] their risks and interestsare different. Once a lot of these have closeddown, the burden will shift to them," Heller says."At some point it may be more than they can bear.
