The Indianapolis skyline underwent a noticeable change this morning, as crews deflated the eight-acre fabric and steel roof of the RCA Dome, former home of the NFL's Indianapolis Colts. The arena has been vacant since the completion of the brand new Lucas Oil Stadium located just south of the Dome. From 2000 to 2007, Drum Corps International hosted its annual "Midwestern Championships" at the RCA Dome. Over those eight years, some 25,000 marching musicians made their way through downtown Indianapolis and the stadium's system of airlocks to perform for drum corps fans. The deflation of the 25-year-old RCA Dome is in preparation of the scheduled December demolition of the stadium. Construction will then begin on a $275 million expansion of the Indiana Convention Center to be completed in 2010. The 2009 Drum Corps International World Championships will take place at Lucas Oil Stadium from August 4-8. Photos by Johnny Gilbert, Sid & Linda Unser, Jessica Payne, Bob Bivens, Dan Scafidi.
