We learned so much from Dolores, who was very generous with her knowledge and time. We walked much of Harlem north of 140th street and finished the tour in lower Harlem. She pointed out the highlights, discussed the architecture and shared, from her well-informed perspective, the history of Harlem. We did not do Hamilton's house as it was closed, but returned a few days later for a tour by a National Parks Service employee and found it immensely informative.
