In the meantime, this is unofficially the first day of a new season here in Austin: the cool months. We turned the air conditioner off yesterday afternoon in anticipation of a cold front coming through, and by evening it was blustery and delightful. Right now it's 53 degrees and breezy. As the kids went outside on their way to school, they cried out, "Whoa! Frigid!" and acted as if they were being blown back by the wind.
I hope we don't need the AC again till April or May, but we probably will.
