If you want to be truly Zen about this, use your pockets. A jacket with zippered pockets is your best friend. You can stash your phone, ID, and a credit card, and glide through security like a ghost.
I once saw a guy with cargo shorts holding a paperback, a water bottle, and a phone in a single pocket. He looked like a magician. Be that magician. It saves you from the awkward “clear bag” aesthetic if that’s not your style.
What You Can Bring (Yes, Snacks!)
The Amphitheatre is surprisingly cool about food. You can bring one sealed bottle of water (plastic, 20 oz. or less) and small snacks. Think granola bars, fruit, or allergy-friendly items. No outside alcohol, glass bottles, or coolers.
Fun fact: The venue has a pop-up farmers market vibe on some weekends outside the gates. You can grab a local pastry before heading in—just eat it before you go through security. Timing is everything.
