Sunday’s Quad Day brought one of the highest turnouts of participating registered student organizations, or RSOs, in its 40-year history. About 640 RSOs took part in the annual University-sponsored event.

The event showcased RSOs throughout the Quad and past Foellinger Auditorium, representing about half of all campus organizations, said Scott Carrico, Quad Day coordinator.

“We really tried to get as many groups as possible,” Carrico said. “We even talked to some friends in the Union and were able to put up 40 more spots (on the Quad).”

Marilyn Adibu, senior in AHS, said she noticed an expansion in this year’s Quad Day, particularly in the diversity of groups represented. As a four-year attendee of the event, Adibu said this was the first time she saw so many RSOs that were new to Quad Day.

“I love the fact that there are more organizations out here trying to lure people in to the University,” Adibu said.

Despite the scare of bad weather — and even a few rain drops­ — the Quad was packed with crowds of students. But some organization members said Sunday’s event had a different feel from years past.

For the Illini Soccer Club, Quad Day serves as the group’s biggest promotional event, said Meagan Reitz, president and senior in LAS. This year’s crowd, however, felt smaller to her. She said the group received only a few email sign-ups by 12:30 p.m.

Early on, Sara Kamp, counselor for the RSO Camp Kesem and junior in LAS, also said the event felt less crowded and that in the event of rain, the group would have stuck it out to seek out more sign-ups. Despite differing RSO opinions of the turnout, Carrico said he was satisfied.

“I don’t think there’s a difference in the crowd this year,” Carrico said. “We usually expect about 10,000 to 15,000 people, and we’re well on our way to 10,000.”

With a bigger setup, many features returned this year, such as the mist tent, free giveaways and many stage performances. The stage lineup included Legend Dance Company, Ghungroo Dance Company, acapella group No Strings Attached and the rap group Writer’s Organizing Realistic Dialect.

Meera Zukosky, sophomore in DGS, said she spent most of her time in the volunteering section of the Quad but was slightly disappointed that she did not find a group she wanted to join related to psychology. Despite the disappointment, Zukosky left the Quad with high spirits.

“I just love all the energy on Quad Day,” she said.
