Taylor Swift’s long awaited Era’s tour is finally here. The tour—which caused a TicketMaster crash after more than 2 million people rushed the site to snag seats in a single day late last year—debuted in Glendale, Arizona this past weekend.
While the lucky bunch of first concert goers swarmed social media to share their favorite songs, outfits, and moments from the show—including Swift appearing to dive through and swim across the stage—they are also giving their fellow fans a PSA more urgent than brushing up on lyrics from her debut album. The message: stay hydrated, and have a bathroom plan.
