Mom and I had a day to explore, so we went across the Hudson River to see mansions and gardens. We weren't disappointed, either!
We got to Martin Van Buren's homestead just in time to take a guided tour of his renovated house! The ranger was very knowledgeable and friendly and the tour group was small enough to make the tour quite enjoyable. I can't remember all the facts and trivia that was stated on this tour, but if you care to, you can read all about it and see a good picture of the dark dining hall by going to http://www.nps.gov/history/Nr/travel/presidents/van_buren_lindenwald.html
I wish we could have gone up into that tower, but Van Buren did in order to view his estate!
