Did this happen in the Austin neighborhood?
Nope. The school district in question seems to cover the area immediately south of Amarillo.
Actually, I think this is pretty clever trolling on the part of those who are responsible for doing it. To my eye, they're simply calling out the numb-nut clods in the Texas legislature who are more interested in grandstanding than they are in carefully crafting reasonable legislation.
I mean, fairly typical Texas behavior, right? A lot of arrogant bluster, signifying little of real value when all is said and done. This is why "cultural conservatives" can't have nice things: all of their political champions are idiots.
