I forgot to add - if they were to try and send all of those kids home, they would be clogging up the streets and making it difficult for paramedics, police, and firefighters to get around. There are enough would-be storm chasers running around and clogging up the streets as it is, hoping to get their videos up on Youtube or whatever.
I checked. Forney ISD sheltered in place.
Our schools all have emergency plans and seem to have done an excellent job today in protecting our kids.
