The NRA Whittington Center is one of the largest and most comprehensive shooting facilities in the United States. Owned and operated by the National Rifle Association of America (NRA), the centre is located in the Sangre de Cristo Mountains of Colfax County, New Mexico. Ten percent of the 33,300-acre (13,500 ha) site has been developed to include twenty-three shooting ranges, an administration building, a cafeteria, a museum, a library, classrooms, and full-service hookups for 175 recreational vehicles. The remainder of the site provides wildlife habitat at elevations above 6,300 feet (1,900 m) with primitive camp-grounds and remote back-country cabins for hunting, bird watching, wildlife viewing, photography, hiking, mountain biking, and horseback riding.[1]
