Let’s get the boilerplate stuff out of the way. Ariana implored her fans to opt out of bags… or at least suggested they choose small plastic ones. I bought one from her website, but damnitall, it did not arrive in time for the show. Thankfully, I was able to check my tote — containing the computer I typed this on, deodorant and a change of underwear (TMI?) — at customer services. Phew! Anyway, getting through security was a dream because there was nothing to hold it up.
