The Penn relays are four days of track and field mayhem, and the main draws are undoubtedly the sprinting events at the high school, college and professional levels. But on Thursday and Friday especially, the casual Relays spectator can catch a host of lesser-known events, especially three field competitions.

In addition to new runners on the track, this year the Penn Relays will have a different feel. The construction on the north side of Franklin Field, as well as the closure of the South Street Bridge, will bring a number of changes to this year's Penn Relays.

I'm no Fresh Prince, but come May 18, I too will be saying goodbye to the city in whose shadow I've been living for the past 20 years. Since my parents to Philadelphia in the late 1980s, parts of the city have changed a great deal: The Comcast Center tower has nestled itself next to the Mellon Bank building and the Liberty Place skyscrapers.

Tomorrow - for the few students who don't know - is Hey Day, the traditional "moving up" day for juniors. And, in the past, it's also been the traditional "get stuff thrown at you" day for juniors. While this year's crop of juniors weren't even at Penn in 2006, when a then-junior was sent to the hospital after being hit in the eye with an egg, the Ghost of Hey Days Past should still be present tomorrow.

If the Penn softball season were a cookbook, yesterdays games would follow a familiar recipe: start with a manageable opponent, add in a slow start, mix in a comeback attempt, let it sit for a while and you get another nail-biting loss.

It was a once-in-a-lifetime kind of comeback. And truth be told, it very well could have happened twice in one day. Down 10-0 going in to the seventh and final inning of its opener against Lehigh yesterday, Penn looked to be done for. The Quakers were being no-hit by Cory Kent and Jordan Warncke, and only one runner had reached base.

College senior Mary Beth Fender has been applying to marketing research and communications research jobs in Washington D.C., but so far has not received an offer. However, Fender said she is far from the only person she knows who may graduate without a job.

According to convicted felon Robert Hillary King, slavery still exists in America - and it calls itself prison.

Two years ago, Liam Boylan-Pett anchored Columbia's 4x800 meters relay team to lead the Lions to their first Penn Relays championship since 1938.

It's time for students to tell professors how they really feel about them - and now they can do it online.

According to a recent report by The Pew Charitable Trusts, Philadelphians are more optimistic than the rest of the country - even though they consume a record high of cigarettes and have dismal job prospects. At a time when only 20 percent of the U.S. population say the country is headed in the right direction, 46 percent of Philadelphians look forward to the city's future.

With a 7-0 Ivy record, the Penn women's lacrosse team has already taken the title of Ivy team of the year. But it's a little harder to predict the Player of the Year.
