Can we bring water in.

They prefer that it be in a recyclable plastic. And it should be clearthey're reluctant to let you bring any anyting it's a closed container that you can't see through if you're diabetic or medication you should bring proof with you of the medication. I do allow things in but it depends on the guard that depends on the program and what celebrity or elected official is going to be there (mayor ,Govner state or federal senators /Congressman or white house person.You won't know and they don't tell sometimes Security is really tuff). if you have a service animal be sure to bring prescription for animal from a doctor stating the animals actually a service animal and you must have a document showing that it was trained.some of the guards some of the gates really a stretch but every once in awhile you get somebody that wants to be a jerk

Yes, I even bring in a reusable (nalgene) bottle with water every game.
