Wow, that is incredible that the house is still there! You are blessed to live in such a historically rich place.
They are a bit on the hoity-toity side, but if you love history, they are awesome.
If you go to the link above, you see the houses they have in my state, but they also have all the New England states. We knew nothing about them, and just a few years ago, we were in Gloucester, MA and went to the house they called "Beauport", but also known as the "Sleeper-McCann Estate". (you can see it in the link above) Click on the Beauport link on that page and look at the pictures...:)
It is best known for being the focal social point for a group of people around the turn of the 19th-20th century, first and foremost, Isabella Stuart Gardener, who bequeathed her house which is now the Isabella Stuart Gardener Museum in Boston. It is best known to people in other parts of the country for the unsolved Isabella Stuart Gardener Museum Theft in 1990 where they made off with art worth $500 million including Vermeer's "The Concert", and Rembrandt's "The Storm on the Sea of Galilee". We went there last year, and the empty places are still on the wall.
Anyway, we were in Gloucester and decided to tour the house on the Fourth of July, and they told us that if we bundled in the cost of admission, and the cost of being able to watch the fireworks there on the lawn, then for only $20 more, we could get a years family membership in the organization. (it is typically $15-20 bucks per person to tour a single house!) What a deal. They give you a passport book, and each house has its own unique stamp, we visited a a bunch of them. Most of the time, there was no more than one other couple so it was very private. They have 97 properties, and we went to every single one we could...:) That house with the wide floor planks was one of them. We are going to buy another membership in a few years, and do the circuit again...:)
