Once the literal engine that powered mid-Michigan, its absence is definitely a leading factor in the crime in the area. I would know, I used to go to school in the area and I would drive my old Monte Carlo out on those roads in winter. They started demolishing the place in the mid 2000s but some buildings remained in 2009. I remember driving by a building as some forklifts were moving around some crates. I stopped and looked inside and saw whole engine blocks on stands just waiting to be moved.
