A basket of balls at this public course's driving range doesn't cost any more than one at the other county-run courses, but Crandon Golf at Key Biscayne might as well be another planet. Besides a gorgeous tropical setting teeming with bird life, there is a cafe that serves filet mignon (for special events) and coconut shrimp and a locker room with tile mosaic floors. The driving rangeç It's perfect, ringed with pine trees and palms. Flags on raised faux greens are icing on the cake. Buckets go for $6.26 (60 balls) or $3.26 (30).
