The Agricultural Core
Just outside of Pittsburg lays the Agricultural core of the Untied States. Pittsburg is centered in the overlap between the two regions of the manufacturing and agricultural core. The agricultural core begins in Erie, Pennsylvania and extends up to the Great Lakes and West to the Great Plains. Immigrants from Europe passed through Pittsburg to enter the west where there were more jobs and opportunities. Pittsburg is the gateway between the midwest and Megalopolis.
