In fact, the red truck phenomenon has gotten to the point where, at one point, a resident (presumably) dangled a toy red truck in front of the camera each time a red truck passed. At another moment, someone (maybe the same mystery person behind the dangling toy truck) held up a piece of cardboard that says "RED TRUCK IS LIFE."
There's even a change.org petition to start a red truck parade in Jackson Hole.
It's not clear why this Jackson Hole live stream has blown up, but it's entrancing. All of it. The weird Pleasantville Americana of it. The weird internet obsessions with red trucks. Or the tension of waiting for the next person to pass who is cognizant of what is happening at this intersection because residents aren't unaware of the phenomena.
Some are playing jokes in front of it. Some wave to the camera. Some must hate it, because at some point after its popularity exploded a store that Atlas Obscura says is called Jackson Trading Company, asked to have their sign blurred out of the stream.
There is no answer to the why, but you start to feel it once you're sucked into the live stream of Jackson Hole.
