So, will your bag make it through the gate? Ask yourself: is it smaller than a small cat? Is it thinner than a textbook? If you answered “yes” to both, you’re probably fine. If you’re still sweating, just bring a clear plastic grocery bag and hope for mercy. (Don’t actually do that.)
Go watch the game. Enjoy the concert. Laugh at the comedian. And forget this conversation ever happened. Just remember: small bag = happy entry. That’s the whole secret. Now go have fun, bag-slinger. You’ve got this.
