Commemorations are taking place all over the world a century after the sinking of the Titanic. In Denver, the Molly Brown House Museum is marking the anniversary with special tours. Its namesake became famous as “unsinkable” for her heroism after the ship hit the iceberg. Janet Kalstrom portrays Brown at the museum and is on a cruise that is re-creating the ship's voyage. She talked with CPR’s Ryan Warner before departing.
