Brightly colored sails glide across the glass surface of Joe Pool Lake. An early morning foursome swings against a backdrop of emerald fairways. Neighbors greet neighbors as they garden, walk and bike. Generations gather at Grandma's for a Sunday picnic. Fathers, mothers, kids and teachers cheer for Friday night high school football. All of this goes on in the heart of one of the nation's busiest and most prosperous urban centers, all in Grand Prairie, Texas.
