Volunteers from the New Orleans chapter of the American Institute of Architects and Second Harvest Food Bank on Dec. 20-21 built a 30-foot-long cruise ship from canned food, one can at a time. The more than 17,000 cans used in the build were donated by Carnival Cruise Lines and will provide 75,000 meals for the needy through Second Harvest. Carnival also sponsored a six-week-long food drive in area schools that will feed thousands more.
