The cellphone store at 1505 Sheepshead Bay Road slapped up a “For Rent” sign this Monday. There still appeared to be a few things inside, but posters were torn down. I noticed because I saw them a few feet away, lying in the public garbage can under the Sheepshead Bay Train Station overpass. I bet if you go now, you may still see the Boost Mobile signs spilling out onto the sidewalk. But the closure makes me wonder: has Sheepshead Bay finally hit its saturation point for cellphone stores? I don’t know, but this is one down, and 54,682,786,023 more to go. Oh, and no, that guy has nothing to do with it. He was just waiting for the bus.
