The class of 2001 is outtahere.

But first, their parents — and the classes of 2000 and back — return to campus to give them a grand sendoff.

The University’s 245th Commencement caps an Alumni Weekend filled with talks, open houses and fun for alumni and friends of Penn. Highlights include the 23rd annual Alumni Run, a 5,000-meter run — or walk for those who prefer; two days of “Classes Without Quizzes,” which showcase what Penn faculty are up to these days; and the annual alumni picnic and parade of classes on Saturday, May 19.

And then there’s the pomp and ceremony of Commencement itself, with the graduates marching through campus on their way to Franklin Field, where U.S. Senator John McCain will speak on a snazzy new stage.

Look for selected Alumni Weekend events open to the general campus community in the day-to-day listings on page 6. Alumni and friends can visit www.alumni .upenn.edu/AlumniWeekend for a complete listing of Alumni Weekend events.
