Speaking of keystones …
The Army Corp of Engineers uses subcontractors too.
The logo for the Army Corps of Engineers is a white castle on a red background, not a red castle, and they don't seem to have much of an outpost in Greencastle.
Do you have a link to that? I can't find an official page with it … maybe someone just flipped the colors.
