Not only is the trail going cold, but guests on Coast are less and less talking about UFOs and more about new topics such as lost twins.
Guess I disagree that it's going cold. It's evolving somehow.
But there's still more interesting things coming out by increasing numbers of quality sources. Nothing overly dramatic but bits and pieces. Incremental additions of puzzle pieces. I don't see it going cold.
C2CAM is still a trip regardless. There's still plenty of UFO guests thereon.
