My first 2 years of high school, 80-82, was in McHenry, Illinois. If your parents signed a permission slip your ID had something on it that let you use the smoking area. In the winter the heater was so hot we'd often wear shorts(with snowpants to/from school).
In contrast - my last 2 years were in Portland, Texas. They had security guards and all the restrooms were locked except for the pair by the main office. In spite of the heat, I got in trouble for wearing shorts on my first day (as well as for having a mustache).
