ITC got converted into an indoor soccer facility. They erected the soccer fields over the tennis courts. One court was left intact so the owner's son can continue to practice there, he's an aspiring pro.
Club Sport is ok, but the courts havent been resurfaced in years.
Sunset Park, the courts are Rebound Ace, but they're also in deteriorating condition.
Depending on what part of town you're in you might want to check out Darling Tennis Center which is in Summerlin. There are also some parks with some pretty good courts in Green Valley, Summerlin, and centrally located.
