In the senior English elective I teach at a NYC High School, students have just completed reading Toni Morrison's novel A Mercy; since the novel is set in the time of slavery, it was important to me to give the students some sense of how the city in which they live and/or attend school was involved in that trade. Inside Out Tours' New York City Slavery and Underground Railroad Tour fit the bill, visiting sites such as the NYC slave market, slave-holders' homes and abolitionists' homes, and finishing the tour at the very moving African Burial Ground on Broadway and Duane. Our tour guide, Sean, was an expert in his field, presenting the stories of how enslaved people contributed to the city from the earliest days of New Amsterdam. It was a very cold day, and Sean was very cognizant of the fact that my seniors needed to warm up from time time, carefully choosing sunny spots from which to tell his wonderful stories, and draw our attention to buildings and landmarks that many of us had walked past many times without understanding their true significance. My students were unanimous in their praise for the experience.
