Yes Gene and I have heard those show's with Calvin and I believe him to be very genuine.
However I think both him and the Hills got caught up in n a government experiment gone wrong.
You mean government agents dressed like space creatures and floated Calvin and Parker toward their vessel? How did they do that and what the heck for? What sort of craft did they use when chasing the Hills? Certainly not a copter. It wasn't something Barney recognized when he looked at it through binocs. I just don't buy explanations of this kind.
