I was bored and looking through some maps.
Like This One
I Understand why Frodo, Elrond, Bilbo and that lot take a boat, but if a Team of Strong People went to the north of Middle Earth, through the Blue Mountains and Gondolin, Couldn't they just stroll in by Helcaraxe? Or if Sauron and his army wun the war of the ring because all the Elves did a runner, could they then go and take over the Undying Lands by the same route I just Described?
Or they could also go east at the Forests of Harad, and sail a boat from there. How come this never happens? ([A,5] and [M,5] on the Map)
