I watched as the Financial District churned and hummed all around us. Sound emanated from every direction: the staccato of jackhammers cracking blocks of concrete in their search for softer earth; cranes stretching their steel joints to lift rubble from one corner of the street to another; ambulances mazing their way through cars and crosswalks, their red flares howling a loud and urgent incantation. This was a significant contrast to the quiet, insulated mountains that encircled Monticello, or the soft rustling of long grass that surrounded the Whitney, or the haunting silence of Angola.
