10/24: a heads-up

...from Chris about a big traffic jam this morning.  He texted me while he was stuck in it, so I was able to avoid it by doing more of my morning work at home and heading to campus a little later than usual.  Hurray for home laser-printing:  it meant that I could make copies of hand-outs here rather than worrying about getting to school with enough advance time to make them there.
