Do not bring a glass jar that used to hold pickles. This is not a fancy dinner party. This is a park where teenagers scream at wooden roller coasters. Glass breaks. And when glass breaks at Knott’s Berry Farm, you don’t get Cinderella—you get a very angry custodian with a broom and a lecture.
Also, under no circumstances should you bring a bottle that makes noise. I’m talking about those blender bottles with the metal whisk ball inside. The shaking. The clanking. You will be read. For. Filth. I saw a grown man get side-eyed by a 12-year-old because his Hydro Flask had a whistle top. He never recovered.
