Sitting on more than four acres, Pioneer Plaza is a one-of-a-kind experience in the heart of Dallas.  It offers more than 50 bronze statues of cowboys and steers making it the largest bronze monument in the world.  The artist behind the masterpiece, Robert Summers, has other works on display at the Texas Ranger Hall of Fame, John Wayne Airport in Orange County, and the Astrodome.  He had no formal art training.
