The Fox River Valley, City Hall, St. Charles, IL
The Fox Valley is a more rural region within Illinois and Wisconsin that borders the more urban portions of the Chicago and Milwaukee metropolitan areas. This region centers on the Fox River of Illinois and Wisconsin. Around 1 million people live in this area. Despite its rural and largely Republican polity, the people of the Fox River Valley have had a strong tradition of anti-pollution activism, championed in the 1970s by the "Grey Fox," a secretive activist who exposed polluters with various publicity stunts.
Native American tribes that lived near the Fox River included the Potawatomi, Sac, and Fox tribes.
Some of cities in the Fox Valley are part of the rust belt. Within this region are Batavia, Illinois, St. Charles, Illinois, and Geneva, Illinois, which may be referred to as 'the Tri-cities area'.
