I can only think of two things that Lawrenceville (IL) High School is semi-famous for: Coach Ron Felling (my driver's ed teacher) went on to be Bobby Knight's assistant coach at Indiana, and our sports teams are still the Indians, one of the few politically incorrect holdouts in the US.
I graduated from Arvada High School, which later had its 15 minutes of fame for the very same reason -- only we were The Redskins.
Graduated in 1969 which had its own ID. This is not to say we got the whole picture at the time, it was just a "naughty" reference which we figured must have to do with s-e-x.
Just remembered by high school was also used as "Hill Valley High" in the "Back to the Future" movies. They thought it looked 1950s, though it was much older.
