Wisconsin firefighters march into the Capitol, bagpipes filling the rotunda.
Those same firefighters show up here, in a video Matt Wisniewski sent us (On Wisconsin! On America!The kids are all right.)
We'll have much more on the show tonight. And now, pictures, with big thanks to everyone who sent them (send more, please!).
This first one shows the Wisconsin flag upside down, an international symbol for distress. Watch for this in the coverage tonight; there's been an American flag also upside down in the Capitol building.
