In an attempt to lower the temperature on the tunnel debate, we're pulling together a panel discussion that will feature proponents and opponents from both sides of the issue.

The event is scheduled for December 16—still lining up a place—and will feature Mayor Mike McGinn, Seattle City Council Member Mike O'Brien and People's Waterfront Coalition leader Cary Moon from the tunnel skeptics' side, and Seattle City Council Member Tom Rasmussen and state Sen. Ed "It's my legislation" Murray on the pro-tunnel side. Other panelists TBA.

The moderator spot is TBA too, but hey, if we have to go with in-house transit wonkasaurus Erica C. Barnett, we're cool with that.
