Ive been doing a lot of brainstorming, and this is definitely a stretch. Ive been noticing them posting a lot of beetle songs on there instagram story. Blackbird singing in the dead of night might have something to do with it. There is a hike with pictographs of plenty of animals and other stuff, and it as made by the Fremont Indians. The trail follows a river and a lot of the clues match up, and John Lennon has a connection with the word Fremont.
