Memorial Stadium has put heightened security measures in place for the 2013 football season.

Fans will no longer be able to bring in coolers, camera bags, briefcases, luggage or computer bags for Clemson games. Since 9/11, Clemson University police have prohibited backpacks, tote bags, brown paper bags and other large carrying bags.

Still permitted (but subject to search) are purses, diaper bags, medically necessary items, binocular cases and seat cushions.

Large chair-backs also are not allowed, and fans will be asked to return them to their homes or vehicles. Umbrellas and strollers may be checked at the gates and returned after the game.

In May, the NFL Committee on Stadium Security banned all bags — including purses — larger than 12” by 6” by 12.” “Clutch bags” are still permitted into NFL stadiums.

Clemson recommends fans attempt to arrive at the stadium at least one hour before kickoff in case of long security lines. The season-opening game — No. 5 Georgia at No. 8 Clemson on Aug. 31 with an 8 p.m. kickoff — expects to provide especially long delays entering Death Valley.

Three other safety and security notes: fans may leave and be readmitted at designated gates, but will be subject to the same security measures as pregame upon return. Only cars with IPTAY placards are allowed on roads close to Memorial Stadium on gameday, and Clemson asks that all adults have photo identification at all times while children are monitored by an adult at all times.
