The latest Nessie sighting.

Loch Ness monster: new pictures and sighting of Nessie

It looks like waves to me.  That said, it has been a while since there's been a Nessie sighting.  Maybe enough public interest will get another expedition out on the lake to look for the creature.  I happen to be a fan of the "Nessie is a dinosaur's ghost," hypothesis.  Hopefully someday we will know for sure what's going on out in Loch Ness.
