In this Monday, Oct. 29, 2012 photo, Mark Langdale, president of the George W. Bush Foundation looks out at the landscaping 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 presidential center on the campus of Southern Methodist University will feature a library that will include the archives and a museum. (AP Photo/LM Otero)
