The Central Park Zoo yesterday was packed with families, like our own, who had small children off from school for the week. The Hassidic families were out in their sartorial splendor, this being Passover week, the men in long black silk coats and robes and women dressed in sensible skirt suits, their children often dressed in matching shirts or sweaters. The Lovely K was getting overheated just looking at all of them in the 75-degree+ sun. By 4:00, the entire visitor population, it seemed, was congregated around the sea lion tank, where the three pinnipeds put on a show swimming around their small home and sticking their heads out on cue in anticipation of feeding time. Around the outer glass wall of the tank – there were two walls with a drainage “moat” in between – people of all ilk hung their arms over the edge and waited: Hassidic and gentile children whose heads barely cleared the wall, Hispanic teenagers in sparkly blue NY Yankees ball caps, parents hanging back on the top step of three, chatting with each other and letting the sun warm their faces.
