I am a big baseball fan and love to go to ballgames. If you go to the stadiums website it will tell you what you can bring in. Most of the time you can bring a soft side small cooler (lunchbag size), blue ice and whatever you want to eat. (Usually no glass containers) What they do limit you on is liquids..the most you can usually bring in is an empty water bottle. Pre IP we took in a backpack full of junkfood.
All that said, now you can use all of the ideas listed and you will have a very sucessful day! Have fun.
