But I won't say that it's NOT haunted, either.
Sacramento, California saw a lot of strife and death in its early years. When gold was discovered in plenty in the nearby mountains that form the Sacramento Valley the city sprang into being as soon as word got out. There was no law, no order, and most of the population was transient, just there for long enough to buy supplies and head out to dig a fortune. Or, having struck gold, the city was the closest point of civilization you could come to, bank your gold, buy a bath and sleep in a bed.
It flooded to the point of near-total destruction in 1850, a year after it had been born. And in 1852. And 1853. In December of 1861 til late January 1862 there were 44 straight days of rain, not just on the city but on the snowpack of the entire Sierra Nevada mountain range. The snowmelt and rain combined created a 320-mile long inland sea in California's Central Valley, drowning thousands and killing all livestock.
The city persisted, creating a series of dams and locks, dykes along the Sacramento, American, and Feather Rivers, starting an aqueduct to funnel water to parched Southern California, and equally impressively, creating giant "Jackscrews"--wooden propeller-looking things that were used to raise the houses and buildings of downtown some eleven to thirteen feet, and then street by street filling them with river rock and infill until the entire city had been elevated a storey-and-a-half. The city of Sacramento is literally built atop the bones of the city of Sacramento.
The West Coast is notably younger than the East Coast, at least as far as cities go. But I'd say a history like that is fertile ground for a place to be haunted through and through.
The night feeling I loved about Sacramento was an eerie one.
