Every drive down the little road leading to the waste compound, off of north Brock Road? Just south of the new Devi Mandir temple? Driving north and south on the little dirt road, there are a ton of what appear to be driveways, though no mailboxes or numbers.
Check
this map to see what I mean.
Tried driving down one once, but it got too narrow and I liked my paint to much to continue. Another time a small black car came racing out of one and sped off down Twillings. Looking at the satellite image, there do seem to be structures back there, though they may just be houses.
At the north end, there are some standard houses, short driveways, mailboxes, the whole shebang, which you can see.
But, going south from there, there is a much longer road leading to a structure that looks too large to be a house.
South of the City Compound, there is another long road that leads to a clearing with all sorts of things, maybe a bunch of cars? And there are some strange shadows, to be sure.
