Ian was amazing!! He was very knowledgeable and fun. This walking tour is not for the faint of heart! We walked about 21,000 steps this day but learned so much on the way. We felt very safe the whole time and were able to navigate the subway by the end it! Some of our tour mates slowed us down, but Ian made sure we were able to get everything in. Even though it was foggy and a little misty, Ian provided a great tour.
