The AT&T Performing Arts Center's Margot and Bill Winspear Opera House and Dee and Charles Wyly Theatre are both lovely venues to enjoy a wide range of highbrow entertainment ranging from ballet to touring musicals to stand-up comedy to opera. While ticket prices can reach the triple digits, one of our favorite ATTPAC features — especially when the temperatures are also in the triple digits — is free. The reflecting pool outside the Winspear, a slab of black granite with perhaps a half-inch of water shimmering over it, just begs for photo opportunities. Walk carefully across it and you can keep the water from soaking into your shoes. Better yet, do like your kids (or your inner child) and go barefoot. It's not quite the same as soaking in a pool or hot tub, but splashing around for a few minutes before or after a show somehow makes the Arts District experience that much more refreshing.
