President Bush hit the trifecta by picking Dallas's Southern Methodist University to host his library and museum. According to the National Archives and Records Administration, which administers 13 presidential libraries, there's an unwritten rule to having the perfect and well-attended facility, and Bush seems to have nailed it. Archivist Allen Weinstein says there are three keys. First, "location, location, location." Here Bush picked a big city and a site near highways. Second, link to a big network, and SMU is one of the region's biggest. Third: "It helps to keep the president alive." Bush is just 61, and his parents are still with us.
