Our schools are brick but so is my home. I pick the kids up early when tornadoes or even bad thunder storms are coming. So do a lot of other parents, we sign them out as weather.
The children go in the hallway and crouch down against the walls.
We use the closet, and the youngest has her softball helmet.
depending on the severity, we bring in pillows and such.
most folks don’t have bunkers.
Ditto here.
