Don and June Mulford made the first verifiable equestrian Thru-Ride of the PCT in 1959.    In that year the Pacific Crest Trail stretched a poorly marked 2,400 miles from Mexico to Canada. More concept than footpath, the trail was an oft-broken, high-ridge track disappearing regularly from map and terrain. On April 19, 1959, on an empty scrub sage plain seven miles east of Tijuana, with four horses, Don and June Mulford began their journey north to the Washington–Canada border. The Mulfords went to Hollywood for three months immediately after the ride and were featured on network television. June's old press book yields a half-dozen TV-Guide pages, and she recalls, "Art Linkletter was such a nice man. We appeared on his 'House Party' show and he had coffee with us afterward." "High Road to Danger," a syndicated TV show, made an episode on their ride. Even after they had returned home to the Northwest, there was continued TV coverage. A January 1961 TV Guide records their appearance on Portland's KOIN Red Dunning Show. The Mulfords even made a 90-minute movie and showed it around 12 western states for 10 years.
