[Rune Son of Bjarne]

well we are told in the UT that even though Galadriel seemingly assisted Eorl with safe passage, he did not trust that she was a friend. . . (when he came to Gondors aid)
Lorien was feard by both Rohan and Gondor, more or less everybody avoided it, like if it had been a land under the controll of orcs.

It is hard to get contact with a people you are afraid of and do not wish to see.
