 The windows are completely rolled up. I leave the car running with air conditioner full on and lock the doors because you can lock the doors. And so that's what I do. I lock the doors while the car is running with the air conditioned on high full blast as high as it goes while I run into Harris Teeter for like the three minutes or five minutes or however long it takes. But there are many times where I'll leave her in the back seat and she's just laying down and you've got the air conditioner blowing on her.
