The letter also announced an increase in policeenforcement at annual Penn events, cancellation ofthe popular post-Spring Fling block party and arequest for cooperation in these measures fromarea bars and alcohol distributors.

Undergraduate Assembly (UA) Chair William E.Conway, who is also a member of Phi Kappa Psibrother, said both Greek and non-Greek studentsare dissatisfied with the policy, which he saidwould push students into risky situations.

"The Undergraduate Assembly is definitelyagainst it, and pretty much everyone I know isagainst it," Conway said. "This ban will pushdrinking off-campus into unmonitored situations."

According to Metzl, students will still find away to drink, probably in their own rooms withoutany supervision or risk management.

Students said events since the ban compoundtheir concern. During the past two weeks, twoundergraduates have been taken to the hospital forconditions associated with excessive drinking, outof only nine known cases this year, according tothe DP.

A rise in unofficial parties to compensate forthe loss of fraternity and sorority events wouldintroduce new concerns for the Penn community,according to Jeffrey I. Snyder, a senior andformer president of Phi Kappa Sigma.

"Having off-campus parties in our urbanneighborhood may not be safe," he said.

Conway added that off-campus parties might leadto an increased incidence of drunk driving.

Alcohol will almost certainly continue to be apowerful presence in Penn social life, accordingto a survey published in Monday's DP.

94 percent of 280 randomly selectedundergraduates said the policy changes would notforce them to drink less.

Other numbers, though, seemed to promise theadministration at least limited success. 21percent of respondents said they approved of theban on alcohol at official undergraduate partiesand 41 percent approved of the university's pledgeto more strictly enforce state and Penn liquorregulations.

The poll had a margin of error of plus or minussix percent.

Fight for Your Right

Claiming that Rodin and Barchi did not consultwith undergraduates before the ban, students heldthe March 30 rally to draw attention to theirconcerns with the new policy.

Conway said that he and other organizers triedto focus the event on students' lack of input inthe administration's decision, but many of theabout 1,000 students who flocked to the rallymerely expressed anger at the ban.
