During the daytime it's often only the breeze that stirs the nets hanging over the two full courts, not jumpers. With the sun overhead, it is just too hot on these shadeless slabs of asphalt green. And besides, the players are in school or at work. But once the sun starts to slide down, activity picks up in a hurry. South Miami parks department supervisor Lorenzo Woodley oversees leagues for players from ages six to adult. But there is plenty of pickup action here, too, after 5:00 p.m. daily. Charlie Miller got his game here, as well as enough moxie to survive Bob Knight and star for Indiana University. You wanna run? Lace 'em up.
