The shoe in the wall thread reminded me of this story of a house in Farr West Utah being built around a log cabin... http://www.ksl.com/?nid=148&sid=20163924
And while searching for this story, I found another one, this one in Flower Mound Texas... http://www.nbcdfw.com/news/local/186...321927942.html
ironically, both cabins are dated to the 1860's...
Wonder how many more are out there?
