In every state I've ever lived in, school zones were hallowed! Stiff fines accompanied violators.
I once got pulled over in a school zone for doing 25 in a 20 during a school break! I got off with a warning, but the officer wanted to stress the importance of obeying the posting, even if school may or may not be in session...weekends excluded.
