Last year we finally visited the Winchester Mystery House in San Jose, CA. I say finally because as most people know that I am obsessed with the weird things in the world, somehow I had never been there and always wanted to go there! The Winchester Home definitely fits into the Odd category and it is completely worth the visit if you've been trying to decide whether or not to go.
As most know, Sarah Winchester was the heir to the Winchester Rifle fortune and was, pretty much, a nut. She continued adding on to the home for 38 years in the belief that she had to do so to appease the spirits of the people who had been killed by Winchester Rifles. The home additions were very bizarre, including the more well known stairs that go nowhere and stained glass windows on interior walls. She was very creative at designing some weird additions and it makes for a very interesting tour.
I've added this to my list of "weird things you gotta see". This list is still just in my head, but maybe I'll actually write it all down for you one day.
