"At least this wasnít so different from the exercise she got on her nightly patrol back in New York. The problem was that this city was unfamiliar ground. The buildings didnít match together well, the skyline was jarring, didnít flow. Back home, traveling from rooftop to rooftop wasnít much harder than running, with the use of her grappling hook to move her every minute or two. Here, it was a jerky, stilted exercise, slow, awkward, demanding use of the grappling hook for nearly every building."
