In his biography of Abraham Lincoln, Henry Ketcham writes:

It will thus be seen that up to his youth, Lincoln dwelt only in the wildest of the wild woods, where the animals from the chipmunk to the bear were much more numerous, and probably more at home, than man.

With what overall impression of Lincoln's childhood does this excerpt leave the reader?

It was isolated.
It was cold.
It was troubling.
It was frightening.
