That is a very common claim, recall the sheriff seeing 50 coming in off the ocean? A CG ship was trailed?
So let us say NONE are coming by ship. That means more people are physically in the US launching SUV sized drones and absolutely no one has seen the people launching them, nor the drones being moved to and from the launch sites. And this is happening everywhere. NJ is relatively dense, unlike Wyoming. No one has reported seeing an SUV sized drone being carried around to a launch site, anywhere. No ring doorbells and other cameras have seen them. These people seeming scattered across almost every state are damn good.
