A. "Sears Routing Office" is probably not its official name. Since I did research online and there is no information about it. B. There is no sign out front or anywhere else on the ground saying what the building is called C. Sears is going out of business anyway.

Therefore, I am resolving this note since there is nothing to add to the map. If someone wants to come along and figure what the place is actually called though, feel free.
