Flying the route from LGA-LEB the other day, heard this with BOS Center after a Cherokee pilot (rather sheepishly) called up and asked for flight following and a vector over or around Bruswick airspace (good airspace to avoid). BOS: Roger, have your request. Climb and maintain 4,500, I'll have a hand off for you in a minute. Long pause. BOS: Cherokee XXX, did you copy Boston? Short pause. BOS: I said climb to it, not squawk it!
