I've heard a story that different kinds of wood treatment were utilized on different pieces of wood as a part of a project with the university on that cabin, and it was inspected over a period of time to see how well they performed.
For what it's worth, Burger King closed in early 2005. I've been told that towards the end there were some significant problems with the sewage on site backing up due to grease build up, though I don't know if there is any truth to those stories.
The lot was used for overflow parking for StrangeBrew/Coldstone for quite some time, and the building reopened in some form as a church for a while as well I remember. I was once told that the developer was willing to let anyone who wanted to have the cabin have it basically for free as long as they moved it (though moving a structure can be fairly expensive). It's also my understanding that while the building was torn down, a good bit of the wood inside (such as the exposed beams) was salvaged for another construction project, I seem to remember hearing it was in 'that town up north'.
