Well, that is certainly NOT DeKalb County Schools. They have this annoyingly bright video sign at Austin. They run this thing 7x24. Nonstop. And it flashes. Not seizure inducing, but annoying. Certainly it is nice for the kiddies to see their name/birthday out there for all to see. And it may be helpful for parents to get a clue about upcoming events while they sit, all but parked, waiting to drop kids off. Almost like there is no other way to let them know. Like maybe a web site, text message or email.
Knowing that the school system is its own sovereign government you can be certain there is nothing the city can do, but is it possible to negotiate with the school? Maybe they could turn this thing off from about 6P to 6A when there really is no one around for them to "inform." Seriously, is that asking too much?
