tweeting about what the obamachron will do to deter the displaced geese that wander over from the drained wetland across the street. i speculated maybe anti-goose drones, another said dogs. that would not be good public relations, but i recall a man-dog chasing birds (and me and my dog) off 63rd street beach. either side of the beach was bird sanctuary. it may not be drone or dog, it may be laser, or repellant spray, or faux-predator ultrasound.
