About 300 Harvard graduates revisited their old haunts yesterday for the Harvard Alumni Association's (HAA) Return to Harvard Day, an annual event for alumni to witness current undergraduate life first-hand.

"We're trying to invite people, specifically [those in their] reunion years, to sit with classes and see what the education is like," HAA Assistant Director of Junior Relations Susan M. Marcy said.

Return to Harvard Day is a chance for alumni to involve themselves with the College on another level, said Kristin B. Curtis, HAA staff assistant for classes and reunions.

"Some are active with their class or reunions, but they don't really get to see students," she said.

Because reunions take place in early June, after exams and classes are over, alumni usually do not have the opportunity to observe student life at these times.

The day also provided a chance for graduates to reminisce about their pasts on a beautiful day in Cambridge.

"It was an absolutely glorious morning," George L. Campbell '44 said. "The Yard looks as great as I've ever seen it."

The alumni, who graduated between 1929 and 1994, started their day before 9 a.m. with a "Musical Morning Prayer" before heading off to a full roster of four courses.

They selected their schedules from a wide range of course choices, including Foreign Cultures 48, "The Cultural Revolution," Religion 42, "The Christian Bible and its Interpretations" and History 1653, "Baseball and American Society."
