Barnum's Kaleidoscape

PT Barnum once said nobody ever went bankrupt underestimating the intelligence of the American people, but the legendary circus owner was also smart enough to know that it takes a lot to impress New Yorkers. His latter-day heirs have prepared a compelling spectacle of clowns, trapeze artists, jugglers, crossbow marksmen and other purveyors of unimaginable thrills. All in a corner of midtown where the big tent is usually reserved for fashion runways - perhaps that's why the circus is promising gourmet snacks.
