I know this is a long shot, a very long shot, but stay with me, I live in a small village, about four years ago we started having a gang of 11-14 year old hanging around outside our house and using the bottom of our drive for skateboarding and bmx-ing, I lost it with them several times, I even got home one day and caught one right up by the garage. Eventually I decided to go and have a chat with them and told them how it feels to have lots of people hanging around outside. I showed them some respect and they showed me some respect and they went away and have never returned.
