Even looking at Tempe Beach Park's Splash Playground in the off-season, when it's dry and quiet, we get a pang of emotion. Over many summer days when the kids were toddlers, they'd laugh and tread the shallow canals of the park, swim diapers swollen with water. Then they'd cry that they were cold when a slight breeze hit them, even when it was 110, and we'd give them a towel-wrapped hug. As the summers rolled on, they got too big to ride the backs of the water-spouting blue whales. They lost their fear of the thunderclaps and "lightning" on the rainstorm stage — but enjoyed it more. They'd have wars with other kids on the water-shooters, chase each other on the slippery surfaces, and try to act brave if they stubbed a toe. We came less frequently once the kids learned to swim, and only the younger one went to the park last year. But the memories of this simple, magical playground linger long after the end of summer.
