C. is working at Andrew's vacation program this week. When he got home today he said they've really beefed up security. "Beefed up the security" means they're keeping the exterior glass doors locked all of the time instead of most of the time, so parents have to fish their key cards out of their wallets or purses or glove compartments in order to buzz themselves inside. If parents don't have their key cards or if their key cards have stopped working, they have to try to attract the attention of people inside to come get them. That's easy to do if there's anyone in the hall because the door and the wide panels flanking the door are made of glass.
It will be the same here in the district, too, no doubt. The new superintendent has sent out an email saying the district will be increasing security measures and asking us to be patient with the coming "inconvenience."
