A few blocks from where I live there is a nondescript green building (link to google maps/streetview). It has bars on all the windows and doors, and all the windows are sort of frosted so you can’t really see inside, although you can see that in a lot of places there are boxes piled up against the windows that go all the way to the ceiling. The construction is basically cinderblock bricks. The building is so agressively non-descript that it took me over a year to notice it was there at all.

The best part about this building, when you finally do notice it, is the name on the doors (on signs on the other side of bars… You can see the signs in the google maps thing I linked to, but you can’t read them…). The name is Scientific Research Co.

Clearly, if ever there were a building with a secret zombie lab in the basement, it is this one. That notion is what inspired this fort.

After I did this drawing, I googled Scientific Research Co. not really expecting such an obvious secret government lab to have a website, but it turns out they do. I note that “a full service fabrication facility serving manufacturing customers across many industries including transportation, heating, electronics, medical, aircraft, machinery, and recreational equipment” would be an excellent cover for a secret underground zombie (or better yet, robot) lab. Large deliveries of metal and machinery of any description would pretty much go unnoticed…
