I'm very interested in this stuff and sort of believe some of these lake monsters and such things could be real. There are just so many sightings and things.
However I don't think the Loch Ness Monster or Bigfoot are real. I sort of believe in the Yeti though because there have been tons of sightings of it and Tibetians accept the Yeti's exsistence as fact...Plus there is still lots of land in the high, cold, dangerous mountains in Tibet that I believe there probaly is at least some unknown species living there....
And as for sea monsters...Well, much of the ocean is still unexplored, there is a possibility that there could be something down there...Maybe I'm just hoping there is

That would be pretty cool if they found something.
