Recently, my dad showed me a news article about the coolest REAL log cabin ever. It was an old, fallen down building purchased for 100 bucks in Missouri and took 10 yrs to restore/rebuild. The builder, Richard Aiken, did a fantastic job restoring this structure.
I particularly loved his door, which I based our log cabin door from.
We put the hinges on the outside (yeah, not correct), because it was easier. I also prefer the look.
