Like many deskbound Manhattanites, I take a slightly desperate pleasure in exercise — in my case, jogging along the Hudson River. I'm savoring the last warm days of summer before the chill sets in and I resort to the treadmill. (Cold-weather jogging seems to annoy my lungs.) The waterfront has grown dramatically more attractive in the nine years I've been living in Chelsea. I particularly love the short stretch of beachy boardwalk that goes south of the Holland Tunnel pier. As Justin Davidson wrote in New York last year, these parks are beautifully suited to people who actually live in the area; the fussily curated High Line, by contrast, seems geared more toward tourists. A few quick photos below, ending with a shot of some promising new titles in the window of 192 Books.
