how to tell if drugs are near your home....

I want everyone to know this and hope this helps with crime in your area. If you are driving around and see shoes hanging from power lines then that means there is more than likely drugs or gangs presence in that area. I was driving to get some lunch today and seen such a site at a house of someone I know and it has been told to me in an earlier time that this woman's son is a known drug dealer. Also this house is right across the street from where some school busses park. Will our police take notice and do something about this? Our neighborhood is a nice one at that and we dont want drug dealers near here.....
