I would be scared thinking that some little kid might be playing in their yard. Maybe you can contact the mayor's office and see if the township can do something once and for all to get rid of them?
At one point I lived on 5 acres in Jupiter, Florida. Off a dirt road--way out with thousands of acres of nothing behind our house. We had pygmy rattlesnakes that would bite my dogs (beagles) and then wild boar would dig up the yards. Bobcats would try to get in the garbage cans. I think what scared me most was seeing a alligator in our lake after it was filled with water. Then a panther would sun itself 3 houses down by the lake almost every afternoon. I did not know we had all these animals out there when we first moved in and think of how I would walk my dogs at night around the yard or hubby and his friend would walk the dogs for a mile at night. I never was so happy to sell the house and move to the beach. Of course now the house is probably worth a million dollars.......with all the growth in that town having 5 acres is hard to get. But all in all country life is not for me, give me stores and people and things to do....I never again want to worry about going outside and maybe getting bit by a snake or something.
