The extra security measures that’ve have already been implemented at pro sports stadiums will impact Iowa’s two largest college stadiums this week.The University of Iowa and Iowa State University and Northern Iowa all host football games this Saturday for the first time since September 11th’s terrorist attacks. U-of-I Department of Public Safety Director Chuck Green says the biggest change is not allowing fans to leave and come back once they enter the stadium. He says they can’t maintain the security they establish at the start of the game if they let people leave and come back into the stadium. There are also restrictions on what you can bring into the game.Bags of any size, such as fanny packs and backpacks are banned along with thermoses of any size. Not all items will be banned.Blankets and sealed bottles of water will be allowed, but will be inspected.Green says it won’t be like an airport where you have to empty your pockets.They won’t pat down or search people’s pockets unless they see something suspicious. Green says fans who like to park their cars outside the stadium ahead of time will face some changes.Any vehicles without a proper parking pass will be towed to another location. Green says the vehicles won’t be impounded, they’ll simply be taken to another location. He says fans won’t see anything flying over the stadium as the FAA airspace restrictions will be in place.Iowa State interim Department of Public Safety Director Jerry Stewart says many of the same restrictions will be in place in Ames.Stewart says they’ll check all parking permits carefully.Stewart says there are many other security measures that he won’t publicly discuss. He also says it’s a good idea to get to the game early. Kinnick Stadium in Iowa City has a capacity of 70-thousand fans, making it the fifth largest city in the state during games. Jack Trice stadium in Ames has a capacity of 43-thousand. University of Northern Iowa D-P-S Director Dave Zarifis says things are a little different in Cedar Falls. Zarfis says coolers and bags have never been let into the UNI-Dome, so there won’t be any extra checks needed.They will likely limit access to the Dome before and after games. Zarfis says they also don’t have the same worries about parking near the UNI-Dome, as most of the lots are away from the building.The UNI-Dome in Cedar Falls has a capacity of around 16-thousand.
