I grew up in Hershey, and still visit my dad there often. Nice work on the colors and iconic stacks. The old factory (which is now an office building) didn't have much in way of signage, but does still have the old bushes in front which spell out "Hershey Cocoa". Extra points if you put a roller coaster or the "Kissing Tower" (with the flag) in the background. The Reese's plant is just down the street if you need a place to ship the chocolate.
BTW, the siding by the silos near Zoo America is where they used to unload the animals when the circus train was in town.
