Signs saying “Why didn’t you walk?” and “Your car pollutes the air I breathe” were flashed at motorists departing campus in this 1970 scene at the new UW-Green Bay. The Ban the Car campaign was related to that year’s inaugural Earth Day celebration and sought to draw attention to modern society’s addiction to oil and gas-guzzling methods of transportation. (Among the green-minded picketers that day was Urban Analysis major and future community housing administrator, Alumni Association president and Pamperin Hall namesake Keith Pamperin, second from left.)
In fairness, the person who owned the Corvair in the foreground probably DID walk quite a bit. When it broke down.
