That's really dangerous. You can't call the cops out when you hear morons acting up? You should call though, that's really a hazard as well as an annoyance. Maybe if the area/road becomes less fun for the nutballs, they'll stop doing it. If I were you, I'd try to get some of their license plate numbers down and when you call, you can give a description. It may seem nosy but it's your street and where you live, those guys could get hurt. :/
