On August 5, we will explore the restoration of items and icons in New England, from Ford Broncos to a historic pier. Nicole Estaphan meets the group that recently restored a "ghost" sign in Boston, which advertises a local company that has been in business for 200 years. She also visits New Bedford's century-old Zeiterion Theater, which has undergone a massive restoration, and Commonwealth Pier, which recently underwent a 10-year renovation.
