Now that you mention WWII and scrap metal You've made me wonder if Kurt Vonnegut went to school there. Then I checked and He's from Indianapolis where his family were brewers. and so it goes......
I misremembered :)
Eldo, air flow/movement was the name of the game in building climate control before the new more efficient systems came into being. This is why there are transoms, high ceilings and lots of windows.
It was a set up attack the substitute teacher was involved. She held me and my attacker back at the end of class. Then sat there with a smirk on her face until I asked what she held us back for then she got up and walked out. The boy attacked me yada yada yada got me in a headlock under his left arm and dropped to the floor. After that I couldn't move. We were in the county children's shelter together. I think most there was 6 or 7 of us from the shelter in that class. It was 1st grade. He had been recruited to do this to "toughen" me up. The reason is the people doing this assumed I was being too fearful of fighting not recognizing that I was being defiant in refusing to do anything they wanted me to. It was the only way I could resist/fight back against the abuse I dealt with 24/7.
Turns out I recovered movement.
When I was a kid in Jersey I noticed that Sumac was always the first plant to pop up on any newly cleared spot. We called it poison sumac. It was only as an adult that I learned there are edible forms of the plant that are used for food and many other things.

Some species formerly recognized in Rhus, such as poison ivy (Toxicodendron radicans, syn.Rhus toxicodendron), poison oak (Toxicodendron diversilobum, syn. Rhus diversiloba) and poison sumac (Toxicodendron vernix, syn. Rhus vernix), have the allergen urushiol and can cause severe allergic reactions. Poison sumac may be identified by its white drupes, which are quite different from the red drupes of true Rhus species.
