I've been commuting again for the last month or so. My route takes me by an elementary school. I wasn't sure if they had started yet or not... until this morning. The answer is they were not open before, but they are open for business now. Kids, cars, parents, everywhere. It was kind of fun today darting between cars, riding on the other side of the road (small side-street), but I could see where it could get annoying, if not dangerous, pretty fast. I'll have to put together a different route.
My rear tire has a slow leak. It will go almost flat overnight, but I can pump it up in the morning, and it's still good for the ride home. Gotta work on it one of these days. I need to take the tire off anyway so I can measure my rims to determine which new tires to get. I currently have 700x35's on my Trek hybrid, I'd like to get something narrower -- as narrow as my rims will allow according to the red & green chart on this page:

Weather was perfect again. About 62, sunny, no wind.
