The event will begin at 1 p.m. Sunday to recognize the National Guard's support of the war on terrorism since Sept. 11, 2001, and their response to catastrophes across the nation, including the Hurricane Katrina relief efforts in Louisiana and Mississippi.

According to Penn State's newswire, live.psu.edu, the university expects more than 20,000 National Guard members and their families to be a part of the giant tailgate and other activities.

As part of the ceremonies, military equipment will be on display along Curtin Road, which will be closed beginning noon Saturday to 6 p.m. Sunday, said Clifford Lutz, assistant director of Penn State University police. University Drive between Hastings Road and Park Avenue will be closed from 8 a.m. to 5 p.m. Sunday.

Porter Road is expected to be congested throughout Sunday from 8 to 10 a.m. and also from 5 to 6 p.m., he said.

Parking is prohibited at the Bryce Jordan Center and Beaver Stadium for the weekend because of the event. Visitors can park on campus in any parking deck or in the Orange Lots in Graduate Circle, Lutz said. People planning to attend Penn State soccer games can park in Lot 83 North, the Physical Plant lots or the East Parking deck.
