Members of the OPP Crew work to place floor mats to build the THON dance floor in the Bryce Jordan Center on Penn State's University Park campus. The crew has been busy since 5 a.m. transforming the BJC into THON Central for the weekend. Doors open at 4 p.m. and THON kicks off at 6. Those who can't be there can watch via live webcast from College of Communications students. For details, visit live.psu.edu/story/51477 online.
