If you happen through Albuquerque, NM, on your ghost tour, there's an abandoned mental hospital in the north valley that's rumored to be haunted by the tortured souls of its former patients. It's the complex of buildings shaped like a "P" in this satellite photo from Google maps.
The caretakers of the property don't take kindly to ghost hunters, but some fearless folks have managed to sneak in and get some photos -- you can see a great slideshow right here. The place has an interesting history -- apparently it was a stagecoach stop back in the 1800s, then became a tuberculosis hospital before being converted into a mental hospital. I have some friends who stopped in there for a yard sale (!) just before it was shut down completely back in the late '90s or thereabouts, and they said it was unnaturally cold inside and extremely creepy. There are crazy rumors of a mad doctor performing twisted experiments on his patients and of a black shape that roams the buildings.
We here at Scary Haunted Travel Guide don't condone trespassing, we only report on the haunted sites.
