[Isowen]

A very good topic. I think that although the ring could be easily misplaced, Sauron did not expect to be destroyed and the ring taken from him by a man (and he doubted the strength of men!) But I think it was also quite clever, as the ring was indestructable, and I don't think Souron expected anyone to come into Mordor and destroy the ring, as that is the only way it can be unmade.
I'm not exactly sure why he chose to bind himself to a ring but I do understand why he chose something he made; because not many understand such a thing and he knew (or so I think) that if he was destroyed, he would always have the ring to bring him back to his old evil self
