Alternate "Hiding the Ring" strategies

[Tuor in Gondolin]

In a more specific example, Deagol found it after so many years under some mud in the Anduin. Whop knows? Pearl divers from Lindon?

Rats. I forgot about that. Although I've thought that a reason (surprisingly missed
by JRRT) for the nazgul fear of going over water was the influence of the
vala there.

But one point above about the Ring's existence gnawing on elves and men's
greediness/desire for power. What if Gandalf
had had Frodo immediately head west to dispose of the ring without
elves, men, bad wizards, etc. (other then Gollum) being aware of it?
Gandalf could borrow a boat from Cirdan without specifying why.

Then get Ulmo to set up a cordon sanitaire.
