Pio Pico was the last man to govern California under Mexican rule. His house "El Ranchito" is located at the corner of Pioneer and Whittier in the city of Whittier. Pico was a wealthy man, and apparently, he liked to party. Michael J. Kouri, author of "True Hauntings of the San Gabriel Valley," says he still does.
"Pio has been seen there many times. Sometimes they hear the sound of the clinking of glasses in the dining room, as if he's having a party. He was quite the entertainer; he loved to have lots of people over, and it's just a very creepy place. But it's really cool."
You can visit El Ranchito at Pio Pico State Historic Park, at the corner of Pioneer and Whittier. No promises that you'll see the ghost of Pio Pico, though.
