I believe in Big Foot. And Nessie. And Champ. And Mothman. And the Jersey Devil. Etc. On and on. Or at least, I believe that we haven't *disproven* their existence, and so I reserve the right to believe that they are there.
I love shows like Monster Quest and Destination Truth. (I also love Ghost Hunters, and to a much lesser extent, Ghost Hunters International. And Ghost Adventures, Most Haunted, Paranormal State...are you sensing a theme?) Anyway.
My person favorite, the one nearest and dearest to my heart is the Meg. I'm a predator fan. I'm a shark fan. Jaws not only scared the crap out of me, it awakened a life long love of sharks. I adore them. I would *love* for us to discover a population of Megs out there. It is my secret geek wish.
