Your concern as I see it is two-fold: the safety of the children playing in the street, and the potential damage of residents' property (regardless of whether cars are parked on the street, in the driveway, or in an open garage). Damage isn't limited to just the cars, it could just as easily be a broken house window or exterior light. The days of playing in connected back yards disappeared with the erection of privacy fences, which puts today's kids in the front yard and street to play. There are no Greenshire covenants being violated by the play, but I can offer how our street handles this play: there are always adults out supervising, interacting, observing. If a car comes on the street, someone yells "car" and everyone respectfully moves to the side. If damage to personal property occurs, there's no doubt how it happened, who was involved, and how it will be fixed. Try hosting a meeting at your home of your street's residents. There is a wealth of information from the NTSA's website on the danger's of distracted driving and a great article from Reader's Digest (rd.com, Oct 07 issue). You can't regulate people's behavior, but you might be able to educate them to want to change behavior. Good luck. If you need any additional information, email me at ghoacovenants@sbcglobal.net.
