Boston {Duck Boat Tour}

In case you are wondering what a duck boat is, it's an old army vehicle that can travel on land and water...
You can see one in this picture:
The captain of our duck boat, Pauly, was very informative about the history of the sites we passed on our tour of Boston.
This is Trinity Episcopal Church. The pictures don't do it justice. It's absolutely breathtaking.
After the duck boat tour, we wanted to try to figure out the subway so that we could use it to get to the airport Monday. So, we decided we'd go to the Boston Aquarium while we were that way.
