Big City has five main boroughs: Johnson, Harris, Wilson, Canal, and Jefferson. A noteworthy factor is that Modula Highway 13 ends in Big City, in the northern area of Jefferson.
Noticeably, there are two large towers located in Johnson. These mirror the Twin Towers destroyed in the infamous 9/11 terrorist attacks. Nearby these towers, on the edge of Harris, there is a building that closely resembles a structure located nearby the Twin Towers before their destruction during the attacks.
