Back in the summer of 2004, I traveled to Puerto Rico for a week with Center for Fortean Zoology Director, Jon Downes, where we were filmed by the Sci-Fi Channel's Proof Positive series, as we searched for the vampire-like Chupacabras.
For a year or so after its initial broadcast, the episode in question was repeated fairly regularly. However, it's now been quite a while since the show was last aired (to the best of my knowledge, at least!).
But, you can now find the episode in question online at Google Video. Click on this link and type in the following, and that will take you to the episode in question:
proof positive evidence of the paranormal - Ep108.avi
I have to say that it was most definitely an extraordinary, adventurous and surreal week, as Jon and I roamed and rampaged around the island in search of the beast, in search of those whose lives had been changed by the Chupacabras, and in search of those with stories of a truly monstrous nature to relate.
And, thank goodness, they let me wear a black t-shirt and not some stuffy suit and tie!
