New to this site, and living in the area. Visited this location 8/16/15. Can verify that the location is still valid, and that there is still quite the puzzle/riddle present in this location.
Be prepared for water, as deep as your ankles, in some locations, and for some cramped passageways. Heavy graffiti at the entrance, but it dissipates further within, except for a few taggers whose progress one can follow.
The "Security" section of this page is incorrect, it is not next to an old person's home, but an apartment complex. I met no difficulty on my trip, but Durham is a city of ill repute, and this is very close to the downtown area.
