This is the first of a series of "earworm" caches with locations inspired by songs I sometimes can't get out of my head.
To paraphrase a Wikipedia article:
"Just a Song Before I Go" was written by Graham Nash while killing time in a hotel room waiting to leave for the airport for a flight home. A friend said to him "You're a big shot song writer, I bet you can't write a song just before you go" and bet Nash $500, so he wrote that song at a piano in about 20 minutes. In a February 25, 2016, interview on The Late Show with Stephen Colbert, Nash stated that he still has that $500.
There isn't any money in it (to start with at least) for you, but we hope the fun of the find is worth the effort.
Terrain rating is higher than your usual PNG due to it's "sticky" situation.
