On a crisp October afternoon—as couple Mary Kate and Sean explored a set of abandoned railroad tracks and snapped photos of fall foliage—Sean snatched Mary Kate's hand and held it over his heart. "It was going insane," Mary Kate recalls, "beating a million times a minute. That's when he got down on one knee. I yelled at him, 'What? Now? Are you serious?' And then I said yes, standing right in the middle of the railroad tracks with no one around."
But on their September wedding day, the couple was hardly alone—they were surrounded by 65 of their closest friends and family, who gathered in the back of Frankies Spuntino restaurant in Carroll Gardens, Brooklyn, to watch them wed.
