Narya and the Shire

[Flame of Anor]

Anyone even notice how it was so hard for Sauron and the Nazgûl to find the Shire, even though Hobbits used to live near the Anduin and Dol Guldur, and all they did was move.

Well i was thinking, since the three elven rings not only give the wielders extra power but also protect their areas: Rivendell is protected by Elrond's ring and Lothlórien was protected by Galadriel's ring, Maybe the Shire is protected by Gandalf's ring.

I mean he really has no place where he actually lives, but he seems to spend alot of time at the Shire, he loves the people there, he thinks the place is beautiful and if there was any place he wanted to protect it would be the Shire because the ring resided there.

Think of it, it's hardly ever been invaded, and it seems to be really hard to find for enemy's.
Also it was only invaded by Saruman after the one ring was destroyed which would have negated Narya's (the Ring of Fire) power and thus made it susceptible to invasion.
