It's almost right across the street from the main entrance of the campus, just off of SW 49th on SW Stephenson St., which borders the back of the building that Walter Mitty's Restaurant is in. It's a little dead-end street that only has three or four houses on it, and it's the one that sits right on the corner (of 49th & Stephenson).
Yup... that's it, my friend! Fuck, that gave me the chills again just lookin' at it! LoL, so many crazy stories from that joint!
My mom worked there for years. I know where most those houses are on that ghosts of N. Portland website. My cousin lived in a haunted house off fairhaven in St. Johns creepy shit went down there.
