I would of course never condone bringing in outside food or drinks… but… A guy I know has brought in a burrito, sunflower seeds, candy, cheeseburgers, an iced coffee, maybe a beer or 2.
And if you're going to attend multiple games, I bet you could wrap the reusable soda cup in a couple 12th man towels and put it at the bottom of your park bag, and I don't believe a single security person will notice for the entire season. Not that I would know from experience, just a wild guess.
Also there are clear cups and maroon cups, and they usually alternate which cup they use each night, but I also bet that zero people would care enough to say anything if you had "yesterday's cup" today...again, just a wild guess.
