The 5.9 (5.8?) earthquake in Virginia definitely rattled the building up here. Nothing so much as fell over, though.
Still, we're all being sent home. Wouldn't complain except I know the roads are going to be a freaking disaster.
edit: Actually, we got out of College Park fast enough to beat the massive traffic jams. Smooth sailing once we got past the construction on Kenilworth. Home by 3!
