Some New Jersey shore towns are opting for an additional layer of protection in the form of steel sea walls placed between the boards and the shoreline as they spend millions to rebuild boardwalks wrecked by Superstorm Sandy,
But not everyone is convinced the costly add-ons will work in the next storm.
