<Terrace Hill is the Iowa Governer's Mansion Address.

You are right. It kept referring to 'the Governors Mansion' and 'Terrace Hill' so I thought they were 2 different places.
But come on this article is obviously rubbish. When something refers to sources it can't name it's usually because they are invented. And nothing plus nothing equals nothing. Repeated claims of evidence that can't be produced are still a mountain of nothing.
