Seattle Kingdome...gone, but still not paid for?

Came across this article in the NYT, looking at NFL stadiums, and they had this graphic to show how much the public has paid towards NFL stadiums.  It was an article targeting the old Giants Stadium that was demolished and turned into a parking lot for the new Meadowlands Stadium, even while the public owes money on the old stadium.

The graphic makes a reference to the Seattle Kingdome that was demolished, and how the public owes more now than when the stadium was first built...partly a result of the remodel to repair ceiling tiles and other items, in 1997, that doubled the total cost of the facility.

How sad...paying down debt to a building that is no longer around.
