I read a book years and years ago called My Side of the Mountain. It was about this boy who lived wild in a hemlock tree for quite some time. It wasn't a very thick book, maybe 100-150 pages, and it was quite interesting.
I live on a mountain in the middle of the forest. During the summer I cannot see any other houses. I have deer and bears around my house all the time. It is pitch black at night. I sometimes hear strange screeching in the woods at night. This is wilderness enough for me! I am looking to move to someplace with concrete and people!
