Don't call the MassHighway folks bad names next time you hit a pothole near Boston. The department yesterday used a new seven-foot-tall screen on the Interstate 93 to shield motorists from the scene of a wreck. The move is to stop rubberneckers that can slow down traffic for miles. This is the fifteenth time the screen has been used in the state and the idea came from Massachusetts Governor Mitt Romney. Of course it's not totally original, folks use similar devices in England. If you have an image of one of these send it along!
