Basketball is a staple activity in New York City. From large venues like Madison Square Garden to local neighborhood courts, you’re bound to find a game of hoops going on. This week, we’re stepping off the court and taking a look at it from behind the lens.    Larry Racioppo is a NYC-based photographer. He’s a regular guest on Cityscape, and this time he’s here to talk about his new book, B-Ball NYC. It features basketball courts in all five boroughs of New York, from traditional hoops to homemade ones, some dating back decades.
