Amarillo is home to a cadre of top-notch museums. Start with the Panhandle-Plains Historical Museum, Texas' largest history museum and sometimes called The Smithsonian with a Texas accent. Then ease into the American Quarter Horse Hall of Fame & Museum, found only in Amarillo. Or the Texas Air & Space Museum, home to the historic DC-3 aircraft found on the National Register of Historic Places. And catch a traveling exhibit at the Don Harrington Discovery Center or the Amarillo Museum or Art. You may not want to head outdoors!
