Look for Cosecha/number station clues

This is a little off the cuff, but some Redditors have tracked down the California desert-looking footage in the projection that happened at Rough Trade record store, UK, on the evening of 4/26. to an abandoned gas station in Yermo, Ca, just northeast of Los Angeles. The last clue could be there.
