I have been taking a daily photo of the Kingdome since February 1st, 2000. 
On March 26 the Dome was imploded.  I was on the 30th floor of the Columbia/Seafirst/BankOfAmerica Tower with my camera.   There are pics and videos of the implosion available here.
Now with construction of the new Seahawks Stadium, the daily photos will
continue indefinitely.
