"In 1867 Andrew Haswell Green, Commissioner and Comptroller of Central Park, recommended that a park be located in Morningside Heights. He argued that it would be 'very expensive' and 'very inconvenient' to extend the Manhattan street grid over the area's severe topography."
Looks like a wise decision from up here.
(The duo descending the stairs just graduated from high school today. The ceremony must have been held nearby, as there were several other fresh-faced, white-robed youths strolling through the park.)
