While in North Carolina a few weeks ago I visited the Card Sandburg Home, Connemara.
Walking into the Carl Sandburg home is like going back in time. Everything is perfectly preserved from the 1960s. It is not a recreation, as Lillian Sandburg actually sold the home and contents to the government in 1968. It's amazing!
Unfortunately the tour of the home is only about 30 minutes long. I could spend HOURS there. There are little notes, photos, and thousands of books to look at. Not to mention all the old items, and collections of things they collected out in nature. What a wonderful place!
