In light of the recent terrorist attacks in Paris, NC State has announced some additional security measures that will be implemented for the last two home football games of the season. The details are here, but the short of it is this: you are probably going to want to head for the gates earlier than you normally would.
Security at the gates is going to be scrutinizing bags, jackets, pockets, etc., more than they have in the past, which is gonna take some extra time. NC State advises leaving your bag(s) at the car if at all possible, because the lines are gonna be slow as it is.
