At 4:30 AM Jeanine and I were jolted from sleep by the sounds of tires screeching under heavy acceleration. The driver of this vehicle had swerved off the road and run over a large rock which became lodged underneath his right rear wheel. We watched for several minutes as he tried to extricate his car and then called the police when it became apparent he was drunk. A total of three Concord Police cruisers arrived on the scene within minutes. The driver was taken away in one car, a second gave pursuit to a car that passed the scene without slowing down, and the third waited until a wrecker arrived to lift the vehicle off the rock and then towed it away. Quite a bit of commotion in our otherwise very sleepy neighborhood.
