There's this horse race, every year the biggest sporting event in Maryland — such a big deal that people turn it into an all-day celebration. The gates at Pimlico, 5201 Park Heights Ave., open at 8 a.m. May 19, and the fun won't stop until well after the last horse crosses the finish line. The all-day party that is InfieldFest features music from Post Malone, ODESZA, 21 Savage, Frank Walker and DJ Vice, as well as a celebratory atmosphere that is without equal. Tickets are $100-$155; the more expensive tickets include the all-you-can-drink MUG Club or the more exclusive MUG & Vine Lounge. For those happy to pass on InfieldFest, Preakness Day tickets run $40-$720; two-day packages, including admission to Friday's Black-Eyed Susan Stakes, run $220-$385. preakness.com.
