Additional commentary.
1. Growing up, loving this house! My great grandma, and my grandparents lived there for a long time!
My great grandma lived in the front part of the house, my grandparents lived in the back part. If you went in the attic you can see the original logs, on the walls and roof. There are names on the wall for a few generations! I was surprised my name was still there, along with all my aunts and uncles!

The very nice gentleman that lives there now was kind enough to let me come inside and reminisce. I just knocked on the door... he didn't know me from Adam. I remember wood burning stoves, and pumping water from the well out back! Great time of my life, and I can't thank the gentleman enough who lives there now!
