The most rewarding change has been the move away from the "bizarre" and the exodus away from the UFO related ideas. It used to be in the old days, the only place to read about hirsute hominids was in a UFO or like magazine. That trend is dying a fast death and I'm glad to see it go.
Now if we can just move research away from cryptozoology and those damn mystery apes, chupacabras, the moth man and Spring-Hill Jack, I'll be a happy camper.
Like UFO research, within Bigfoot research, there are huge divergences in ideas about what UFOs/Bigfoot might be. But that aside, it’s a good interview!
