So, you've got an hour or three to kill at the damn airport and you're sick of people-watching and drinking yet another cup of coffee. You've hit all the stores in Terminal 4, but you're not quite ready to go toe-to-toe with the TSA. We've got the solution, and it's art. The folks at Sky Harbor really have it going on culturally, especially in sprawling Terminal 4, where the 24/7 galleries always have something for the most discriminating and the simply bored to enjoy. In the past year, we checked out a photographic exhibit of our state's magnificent saguaros, as well as atmospheric landscapes by Ellen Wagener and a trippy exhibit of outstanding artists who work with fiber in various ways. But our recent favorite was a multi-media tribute to baseball's spring training in the Valley. The black-and-white photos of the San Francisco Giants (with the Hall of Fame Willies — Mays and McCovey) working out in Casa Grande in the early 1960s were priceless and helped us lose ourselves for a few moments without reaching for our wallets. Art for the masses, indeed.
