Last year directly after my son's final match he desperately wanted some gatorade. I went to purchase some, but all the concessions had closed down. I asked the guy at the gate if I could bring one in and was told "absolutley not - you have to buy it in here". When I told him that that idea was pointless what with there being no place to purchase anything he told me once again that you had to purchase all food items at the concessions. How pointless.
