There are six courts always up for the taking at Roadrunner Park in north Phoenix. No fee is required to use the courts, but it's first come, first serve. The courts were recently resurfaced, so you don't have to worry about a giant crack getting in the way of the backhand winner down the line. On any given day or evening, you'll see hardcore competitive tennis players practicing serves as well as recreational players enjoying a fun game of doubles. There's no need to cut the evening short, because the courts are lighted, and for those who want to practice their strokes, there's a hitting wall available, too. When it's time to cool down or shake off a bad game or two, you can stroll around the park, watching kids play on the playground or dogs walking with their owners.
