Sorry to break it to you, fanboy, but it's highly unlikely you'll ever shoot on the same basket Dwyane Wade has dunked on or throw a football on the same field where Tom Brady once scored a touchdown. But in Miami, you can actually practice your backhand on the very same courts where Serena Williams and Novak Djokovic have played. For two star-studded weeks every year, the best tennis players on Earth descend upon Crandon Tennis Center on Key Biscayne for the Miami Open. But for the other 50 weeks, the same courts where pros vie for million-dollar prizes are open to any hacker with a racquet and the $7-to-$13-per-hour the courts cost to rent. There are 26 hard courts, including eight with lights. There are also six clay courts, two of which are red European clay, as well as two grass courts if you want to pretend you're at Wimbledon. Though you're more likely to see an egret or heron flying overhead in this scenic locale across the bay from Brickell, you might also stumble across Grand Slam champions Andy Murray or Juan Martin del Potro, who often use the site for training.
