Have you ever been to an NFL game? I have. A bunch, actually. But I stopped going because: a) it costs a fortune; b) it eats up your entire day; c) I'd rather watch at home; and, d) you take your life into your hands.
I've seen drunks start fights in smelly bathrooms, the stands and on concourses. I've been called names for wearing another team's jersey in an opposing stadium. I've even taken my jersey off and stuffed it in my cooler as I walked from one side of the parking lot to the other to avoid confrontations with "overly enthusiastic" revelers.
So I feel like stadium security probably has better things to do than toss out some dad who had his teenage son hold his beer so he could take a photo.
