Into RDU from Indy early this a.m. on Northwest. Drive in rental to Chapel Hill and do 75-min brief that felt solid and yet some brain lapses--just slight--that told me something was wrong.

Crowd of many 50-60 midcareer students from two courses (both logistical). Interesting mix of civilian and mil. Q&A especially good and went 45.

Got Last Lecture and nice command coin and signed a bunch of books.

Getting to be a nice regular gig down here.

Heard from spouse: daughter with sinus infection and I begin to wonder about how bad I felt upon waking this morning, the creeping flashes of stupidity and an oddly sore throat after talking.

Having doc call in some antibiotics on the road as trip continues. I don't like to leave the country without some.
