Nessie comes up for a swim
Scotlands' Loch Ness harbors mysteries, if not also a monster.
All of England, perhaps because of the English, is full or monsters, faeries, ghosts, and curiosities of every sort. Perhaps the best known of these is the continuing dispute about whether some sort of sea serpent or lizard lives in the murky waters beneath this loch, and many others, for that matter. Certainly the geology might contribute to the ability of such a serpent to evade detection; not only are the waters stagnant and murky with numerous depths and recesses, but now we know that many of these lochs are connected, underground, by flowing channels or rivers. (This is true in the south as well, for example, at Cheddar Gorge). Who is to say that some shy, if somewhat creatively evasive, critter hasn't been down there? Maybe its just a politician; they can be pretty slippery too, and just when ya think they are gone (e.g. the Labour party) they pop up again!
The lochs are partly a function of tectonic faulting, which splits Scotland in two down the length of Loch's Ness and Lomond. The small valleys have steep, forested sides and logging is quite common in this region; while looking for Nessie in one eye keep an eye on the road with the other.
