Many people tell me that I have big feet (I wear a mens US size 13). But as for Bigfoot, Sasquatch as well as other fables of imagination such as the Yeti or the Abominable Snowman and such I think only exist in the minds of people who consume excess amounts of firewater.
As for "Nessie" (a.k.a. the Loch Ness Monster), I don't believe that, in this day and age, with the available technology (sonar, radar, submersibles, and the ability to drain and create lakes) that a supposed prehistoric monster weighing many tons cannot be located. Add to that the gaggle of "believers" standing around the Loch 24/7 armed with an arsenal of video cameras and telephoto lenses. In other words, the reason we cannot find her is because the damn beast probably isn't even there to be found in the first place!
And if there is one, how long do they live? Since stories of Nessie have been circulating for many, many years, I cannot believe that whatever "she" is has been able to survive for 300 years-unless there were multiple "Nessies" that were breeding-which would only blow a bigger hole in the theory of the Monster.
Finding one may be hard enough, but why can't we find a whole colony of them?
