At my first college football game, the pledge brother of my bf at the time put some whiskey in a ziploc bag and "stored" it in his crotch area. I am not quite sure how he kept it in place, but he had it again in the stadium so I know it was safely smuggled in. The students usually got searched (the guys patted down, the girls purses checked), but those with tickets outside of the student section usually do not. At my first game in the non-student section I was surprised to see how many "grown ups" had their own flasks!
