Want to fly like a bird? Try I.FLY.LI, a flying trapeze school on Long Island, N.Y. The company offers groups the opportunity to make like Peter Pan for parties, team-building get-togethers or corporate events. After a review of the basics on terra firma, instructors with a background in circus performance assist guests on their takeoff on the flying trapeze and man safety lines as they swing through the air (with or without the greatest of ease). Instruction in other aerial arts such as the swinging trapeze, silks and Spanish web are available. For more information, call 516/640-8666, or visit www.iflyli.com.
