Don't you think Lanty this last Question is a bit inter-related with the Ongoing
ranger motives discussion?
First we have to remember that during to WOR,
Shire was basically left alone...by all the cheif protector and chief enemies...and all the depleted people, the
evil baggage, whom no one would give any thoughts made their way towards
the Shire and occcupied the land under the ruler of
Sharku.
My Guess is also the man power, although it is argueble whether this Man-power was there to protect through its history or was it after a specific time that they started protecting Shire?
Well not everyone could entre
Imladris, or else it won't be called a Refuge.
Lothlorien on the other hand was an offically established Kingdom, and thus would have
armies that would protect its bounds, being helped both by the valour of the
elves and the power of
the Ring.
