Miami's most prominent reading series, by current authors of predictably high caliber, is a good way to defy this city's tendency to settle for beauty over substance. And no doubt about it, intelligence more often than not cultivates a singular kind of beauty. In short, good-looking women go to these things, and they probably are smarter than your average barfly. If you spy a single woman at a reading, chances are good she's looking for more in a mate than a walking billfold. And if she's alone, she's either single or her boyfriend doesn't share her interests. All the more reason for you to sidle up and see if she wants to deconstruct Susan Sontag over an espresso.
