158. NEW YORK ON FOOT. Harlem. Looking north at the bottom of the hill that transitions the Upper East Side into El Barrio (AKA Spanish or East Harlem). The two communities are not alike (to put it mildly). The various hills in Manhattan were named when the island was rural, “mostly hills and shrubbery”. The bucolic place names are ironic, Turtle Bay being the most iconic. I have tried walking the boundaries of Murray and Carnegie Hill a few times, but it is not easy to navigate hills in the urban tangle.
