I remember last year when there were concerns about Covid in schools, seeing pix of a crowded school hallway - which I can remember at my public high school during class changes. I think it was in Texas in August and I wondered how they stood it even during pre-Covid times.
I went to a great many schools in my life, both public and private (finished high school at a private boarding girls' school in Massachusetts) and some were ancient and others were brand new. They were still building parts of my college when I went there, lots of mud in the Spring. But I'm guessing that the majority of schools are older buildings and the ventilation must be a huge problem, especially now. I still have bad dreams about the school where I went to 7th grade. I know now that it was built in 1911 since it was turned into offices and they had a big anniversary in 2011, invited teachers and students that had gone there over the years. I can remember in warm weather they'd leave the doors to the fire escapes open to the outside.
But if it was that warm here in New York during the Spring, I can't imagine how it is in Southern states in August - it's often unbearably hot here. When I was in school, I had a summer job at an amusement park and it was hot enough then that the boss would send the mechanics around with "salt pills" for us ride operators. I was lucky that I didn't spend all my time standing out in the sun, I drove the purple train that went through the jungle (woods).
But I've often wondered how workers there stand it now, since we know that it's gotten much hotter.
Its hard to believe we're starting a second year with Covid - which should mean that schools - and everyone else - have had a whole year to prepare. But I'm guessing that, especially in areas that still deny the virus, they're as unprepared as they were a year ago.
