Several motorists had made their way to safety on a road bank when they noticed an SUV slowly being swept down Interstate 10 in Houston.There was an elderly man trapped inside the vehicle.The motorists quickly agreed to form a human chain to stretch out to his vehicle. Working together, they joined hand in hand to fight the water, reach the SUV, and pull the man to safety.It's a story dripping with fairytale overtones that shows the forces of good can triumph over evil. The video of this human chain, which I saw posted Wednesday night on CNN.com, has probably been well viewed by now.
