In this Monday, Oct. 29, 2012 photo, former first lady Laura Bush smiles during a tour of the George W. Bush Presidential Center in Dallas. A 15-acre park at the upcoming George W. Bush Presidential Center will recreate a Texas prairie, complete with a wildflower meadow, a special blend of native grasses and even trees transplanted from the former president's ranch. The park's landscaping, which was completed this month, is a recreation of the kind of prairie landscape that would have existed in the area before it the city was built. (AP Photo/LM Otero)
