ARKANSAS

A surprise to most people, and why we love it. Crystal Bridges, in Bentonville, holds one of the great collections of American art, from Rockwell and O’Keeffe to Kerry James Marshall, in Moshe Safdie’s buildings over a spring-fed ravine. On its grounds, Frank Lloyd Wright’s Bachman-Wilson House, moved piece by piece from New Jersey. Next door, the Momentary shows contemporary art and performance in a former cheese factory. Fay Jones’s Thorncrown Chapel stands in the Ozark woods near Eureka Springs.
