Fort Worth's annual bash, Mayfest, is back and library cardholders are getting a sweet deal: show your library card and get in the gates for zero dollars. The festival is set to take over Trinity Park from May 2-5, boasting a smorgasbord of music, dance, and all sorts of performances on multiple stages, according to the City of Fort Worth.

But, there's a catch – you've got until May 4 to hit up any Fort Worth Public Library and flash that card to snag your free entry pass. If you're not already toting a library card, no sweat, sign up on the spot and they'll hand you a ticket, with no cost attached. Keep in mind, this deal's a one-per-person show, and only until supplies dry up.

Mayfest isn't just about the adult fun either. The Fort Worth Public Library is setting up camp in the Children's Area, probably trying to hook the young ones on reading between rounds on the rides. Given their plush lineup of family-friendly activities, rides that scream thrill, and a spread of food that'll make your taste buds dance, they're calling it 'Fort Worth’s ultimate annual outdoor festival.'
