In the hectic, hurly-burly world that is modern America, it is all too easy to forget life's simple pleasures: a good book, that first cigarette of the morning and getting a group of friends together to build a human tower. The Mapapa African Acrobats, who perform daily at Six Flags (I-44 at Allenton Six Flags Road), are here to teach us the error of our ways with their hyperkinetic stage show. The seven members of this Kenyan troupe jump, flip and dance with reckless abandon, stopping only to erect intricate towers and structures bearing exotic names such as "the Hilitoni" and "Utah" (well, that's more homey than exotic). But "the Ndege Star," that's pretty alien-sounding, and it denotes a sense of danger, too. Live dangerously. Seize Tuesday. Enjoy the bravado of these talented acrobats, then go smoke a cigarette whilst reading. Performances are free with park admission ($38.99 plus tax); call 636-938-4800 for more info.
