I have an excessively long breakaway cable. The way I keep it from dragging on the ground is to give it four to five twists before connecting it. The twists cause the breakaway cable to coil up upon itself. It then lays nicely atop the safety chains with little chance to droop to the ground. Consider it a poor-man's Fastway cable.
