I went to the same school from K-12. They never had a cafeteria either. They opened a hot lunch concession run by mothers using those infrared sandwich warmers and Stewart, later Landshire sandwiches that were in those heat proof plastic bags. Usually were inedible and disgusting anyway as whatever was left over from the previous day was reheated the next and you got cardboard. I was also a latch key kid by the third grade with both parents working. We didn’t have A/C at home until after I started College and my mom was beginning to have her own private summers. I didn’t get A/C until the ’67-’68 school year for 9th grade home room where they had recently built a 4 room addition that had it. Only those classrooms,the front office, and the library had AC. Otherwise most classes still were in un A/C rooms until the second semester of my Jr. year when we moved into a whole, new school. My kids couldn’t comprehend not being in A/C all day at home,school,or anywhere else. Only real taste they ever had of that life was after Hurricane Andrew where we were without power for nearly 2 months.
