Scents and the City
By JASON LOGAN
New York secretes its fullest range of smells in the summer; disgusting or enticing, delicate or overpowering, they are liberated by the heat. So one sweltering weekend, I set out to navigate the city by nose. As my nostrils led me from Manhattan’s northernmost end to its southern tip, some prosaic scents recurred (cigarette butts; suntan lotion; fried foods); some were singular and sublime (a delicate trail of flowers mingling with Indian curry around 34th Street); while others proved revoltingly unique (the garbage outside a nail salon). Some smells reminded me of other places, and some will forever remind me of New York.
