Buy a free standing basketball stand,chip in with others and give it to the kids,on one condition,play somewhere else. It may be a very nice way to settle your problem,and shouldnt break anyones bank account. Chip in and get a chain and lock,so it stays there too.Good luck,i too like kids playing,but the basketball bouncing noise will drive you nuts!
All the kids in our neighborhood want to play basketball in the alley from garage mounted hoops. The problem is damage to the garages from wild games, tresspassing, loud noise from the thumping of the ball, and the bringing of large numbers of kids into the area who do not live there. We don’t know how to solve this and everyone is mad. I wish we could find a compromise.
