WHAT DID YOU SEE? >> DENISE, WE WERE ON A VOTE FOR SOME THREE HOURS THANKS TO THE CORE AND THE UNIFIED COMMAND. WE SAW ONE 200 TON PIECE OF THE KEY BRIDGE OVER AT SPARROWS POINT AND THERE ARE STILL SOME BIG PIECES OF THE BRIDGE IN THE WATER, AND BEHIND ME, SOMETHING THAT A LOT OF PEOPLE ARE EXCITED TO SEE -- THE VISION OF THE SEAS, THE CRUISE SHIP FROM ROYAL CARIBBEAN, HAS RETURNED TO THE CRUISE TERMINAL. >> Reporter: YOU'RE LOOKING AT THE FEDERAL CHANNEL, WHERE THE KEY BRIDGE ONCE STOOD.
