1970-1974 was the hot period for hippies and such. We still had hippies near campus in 1977, many former military.
There was a scene in the movie “Dazed and Confused”, where the teacher tells her students that when they celebrate the Bicentennial, they are celebrating “a bunch of white slaveholders who didn’t want to pay their taxes.” So you can pretty much see there when the rot really started to begin.
