Let’s take a long walk that starts across the Harlem River via the High Bridge. You will hear the tale of the Old Croton Aqueduct then wind back to the gorgeous Jumel Terrace Historic District, Trinity Cemetery (resting place of Ed Koch and John James Audubon), and to hidden Audubon Terrace. Along the way, we will pay homage to Paul Robeson, jazz greats like Lena Horne, the indomitable Eliza Jumel and to NY baseball. Be prepared for many stairs and up to 4 hours of hilly walking (4.5 miles), plus elevated subway train transfers. (Metro North Hudson Line riders can ride down to Manhattan with the guide.) Bring snacks, drinks and a sun hat/light-colored umbrella. Meet at the NE corner of 168 Street and St. Nicholas Avenue in Manhattan, a short walk from subway stations. Rain cancels.
