You probably have to be from the midwest or the plains states to recognize these buildings--grain elevators. Handy, necessary, and dangerous.
CA worked two summers as a high school and college student helping to build the concrete parts of this complex. He's allergic to the concrete dust and spent a miserable time with congestion and oozing rashes, yet he loves the fact that he helped build these silos.
The dangerous part comes in being an amateur and working on a high-rise concrete project, and in the operations after. Just a few summers ago Gigi's friend's son was sucked into the vacuum system of an elevator he managed--it was clogged and he ill-advisedly climbed into the corn to work the clog loose. He didn't survive.
