It looks like a factory that is making Christmas trees.
There is a dividing line between a hospital and apartment housing for (mostly) international students who attend the University of Kentucky. These poor people have to hear and see these giant vent fans spewing God-knows-what into the air. Curiously, the UK campus and this hospital are “smoke-free” campuses. The smokers stand on the dividing line – a trench that sometimes acts like a creek just in front of this belching stack- to feed their habit. Like that “line” is the DMZ or something.
