Inside the Supreme Court, they'll be making history, as the justices hear three days of arguments for and against the federal health-care overhaul.

Outside, they'll be making noise. And camp. And dinner, if Clif bars and apples can qualify as such.

While great legal minds do their thing inside the courtroom, activists, curiosity-seekers and others will gather out front, leading protests and waiting in line to get inside for a peek at the legal battle.

The view from the sidewalk should be just as interesting as what goes on with the justices. We'll keep tabs on it for you here.
