This link won't last more than a week (or at least won't link to the same image for more than a week, but... U of Arizona webcam.

I dropped my son off at school, and fortunately had to return later and discovered the empty parking lot -- he'd walked back home. It's not that the streets weren't plowed ;-) but the nearby bridges over the Rillito get icy.

The airport was closed last night.

All in all, more wintry than when I visited New England a week ago!
