I managed to get rid of them once in MA by letting my 6'6'' son with waist length hair answer the door. He cracked to door open and peered out in a paranoid manner saying "Yesss?......) (he has a very deep voice). When one of them started with the introductory questions he said "wait" pushed the door nearly closed and shouted back into the house "never mind the goat guys, I've found a couple of virgins." When I looked out I saw their backs disappearing down the road. They never bothered us in MA again.
