Governor Jerry Brown has bucked many trends as Governor of California but the one many people won't understand is his decision not to live in the Governor's mansion.

The three-story, 30-room victorian home was built in Sacramento in 1877. Governors haven't lived there since the 1960s and it has since become a historical landmark and tourist attraction.

Tonight, the mansion opens its doors and, for the first time in decades, welcomes visitors to its third floor.

For more on its significance, we're joined by Al Howenstein, the chairman of the California State Historic Governor's Mansion Foundation, a non-profit that raises money to support the mansion.
