Now I'm all excited. Yup, not getting any work done today.
(Actually, we thought someone was moving furniture upstairs. Or that our elevator had crashed. )
UPDATE: Oh, I feel cool. Got to do the "Did You Feel It?" report. Oh yeah.
UPDATE 2: Thanks to Ron for the email - he checked in with Callan and I right away. (Callan's got great coverage, and he managed to find the seismogram of the earthquake from the Maryland Geological Survey. And he was practically on top of the thing. Lucky!)
