A brief, loving portrait of Provincetown, the town at the very tip of Cape Cod, by part-time resident Michael Cunningham (whose The Hours, Item NYC67, won the Pulitzer Prize). The notion of a walk, really, is just a convenient way for Cunningham to wax eloquent on Provincetown's early history and its development as a home to artists, bohemians, kooks, and, more recently, to a large gay population. He especially focuses on the breathtaking and uncanny beauty of the town's environs.  (USE254, $16.95)
