As I noted in my blog yesterday, I'm in Eugene, OR, visiting my dad. He's in the hospital after having a stroke. It's not life-threatening, but he's paralyzed on his left side. (And he's left-handed, alas.) It's going to be a bit hectic here, and I have other things on my mind, so I'm going to take the week off. I'll go back to daily blogs after I return to Maryland, on Wednesday, May 18.
