Location remains undisclosed: We're off on yet another mission of national import. It will take us to an undisclosed location in Aberdeen, South Dakota.
We don't expect to post again until some time this weekend. That precise time remains undisclosed.
On Monday, we'll start the third week of our four-week report, Where the Test Scores Are. Next week's reports will explore this theme: Where the Achievement Gaps Are.
Also next Monday: the first debate. We'll provide some historical background.
