Sleepless in Indianapolis

Between the long string of intense thunderstorms that rolled through the area last night, the frequent wail of warning sirens, and the even louder and just as frequent alarms from our weather alert monitor, it was not a restful night. However, I did learn this morning that I could get through a two-hour session of my Seminar in Property Theory on no sleep. The students looked as bleary-eyed as I felt, though I don't know whether that was because of a sleepless night or just the ordinary response to two hours of property theory.
