In the far southeast corner of San Diego county lies a small town, Campo. Campo is well-known historically for two things - the ancient Gaskill Brother's Stone Store, where a shootout occurred in 1875; and for being the nearest town for the southern terminus of the Pacific Crest Trail ("PCT"). The PCT starts at the United States-Mexico border, and as Campo is only 1.2 miles from the border, it is the jumping off point yearly for PCT through-hikers seeking to travel South to North on the trail. Campo is also home to a unique and hands-on museum, the Pacific Southwest Railway Museum. The museum is the main location and headquarters for the Pacific Southwest Railway Museum Association ("PSRMA"), which was founded in 1961, and has been the preeminent group for railroad enthusiasts in the greater San Diego region for over fifty years. Since 1980, the museum has been open at the location in Campo, and from that point on has been a place where old railcars and engines are stored for public visitation, a place with an excellent interpretive museum about the rail history of Southern California, and on occasion, a place that provides tours along the rail line from the old Campo railroad station (adjacent to the museum) on the trains that the association owns and operates.
