Probably not much. But it’s a small world, and as it happens both Kenyon and the 43rd president are among the clients of Cambridge, Mass. landscape architecture firm Michael Van Valkenburgh Associates Inc (MVVA). When Dubya’s presidential library opens on May 1, it will be surrounded by “a sustainable, native Texas landscape” situated on the campus of Southern Methodist University in Dallas. MVVA also recently designed a master plan for Kenyon’s campus.
