The RCA Dome never felt so good to the Super Bowl champion Colts. After a rain-soaked victory in Miami the night before and then a frigid, bone-numbing homecoming parade through the streets of downtown Indianapolis on Monday night, the Colts finally arrived at the stadium for a raucous celebration with their fans. More than 40,000 of them, just as loud and boisterous as they were when the Colts left the Dome two weeks earlier with the AFC championship, welcomed them home, reveling in the city's first major professional sports championship in more than 30 years.
