This game started about 80, was probably in the mid 80-s by the third quarter. I stayed cool by bringing a blue bandanna, wetting it every 10-15 minutes, and draping it over my neck and under my cap. Probably looked goofy, but I stayed comfortable the whole game. Also brought a spritz bottle of sunblock for the arms/hands.
Several fans in my area with little or no preparation were well lobsterized by the end of the game, however.
