From wikipedia:
"Last Train to Clarksville" is a rock song. It was the debut single by The Monkees, released August 16, 1966, and later included on the group's 1966& self-titled album, which was released on October 10, 1966. The song, written by Tommy Boyce and Bobby Hart; was recorded at RCA Victor Studio B in Hollywood, on July 25, 1966 and was already on the Boss Hit Bounds on 17 August 1966. The song topped the Billboard Hot 100 on November 5, 1966.
The lyrics tell the story of a man phoning the woman he loves, urging her to meet him at a train station in Clarksville before he must leave, possibly forever. The Vietnam War was raging at the time, and what was not made explicit was that the song was about a serviceman headed for the war zone.
Cache is along the railroad tracks. Many earlier caches here have been archived, so I thought I'd replace a few. Most are on the trailsode of the tracks unless otherwise noted.
