I'm not quesy about Bigfoot-UFO stories; and having personal contact with some who've had these kinds of experiences, what can one say? These stories exist, and, like "alien" abductions, they're here. What to make of them; hmmm. But I am fascinated, and there seems to be a decidedly firm relationship between some sort of Sasquatch like being, and UFOs. Or, what we interpret as Sasquatch like beings, and UFOs.
The CryptoZoology.com site has an article on Bigfoot-UFOs; interesting, but I don't think we see things the same way.
