On Saturday we took a tour of the Mayowood Mansion, the home of Charles Mayo, one of the brothers who started the Mayo Clinic here in Rochester, MN. Out on the veranda (which you can see if you follow the link, above) there were a number of different versions of Adirondack chairs. I'm sure they aren't original to the house but I think they are copies of chairs that were there. Here's a rocking version that I've never seen before.
There was some amazing pieces of original furniture inside the house but they don't allow photos to be taken so I didn't get any and there don't seem to be many interior pictures of the place online at all.
