LPGA legend Annika Sorenstam, PGA Tour member Briny Baird and PGA Teaching Pro and U.S. Veteran Don Vickery, the first and only double amputee Class A member of the PGA of America, took part in a unique challenge called “Chipping for Charity” to benefit the Intrepid Fallen Heroes Fund on Monday morning. Each player hit 10 floating golf balls from the rooftop of a 40-story building at Waterside Plaza in Manhattan in an attempt to reach a floating bulls-eye target in the East River. PF Changs is offering everyone in the U.S. a free order of their signature Lettuce Wraps and will donate up to $100,000 to the Intrepid Fallen Heroes Fund based on the golfers’ accuracy.
