NYC and Boston (and the US in general) are lucky to have had an architect of his caliber designing green spaces...we could use some more of those to catch up with Europe ;)
Also interesting idea here...correlates with talk is cheap...but wonder if there is a word or phrase that captures this idea from Bushnell, the Olmsted family pastor:
"The most important and constant influence that people exerted on each other, Bushnell believed, was not verbal, but rather a silent emanation of their real character that showed in their habitual conduct and made itself felt at a level below that of consciousness."
