If you're ever at the rest stop on I9 on a full moon. You can sometimes hear the howls of Wolves, and sometimes those howls are from truckers playing the Skin Flute.
So if you're out there, and a voice from the forest asks if you want to hear the "song of my People". That's your cue to get ready to play some werewolf's instrument.
Ahh People of the Night...such music they make.
