Rose Parade marches in Pasadena, Calif.

PASADENA, Calif. (WLS) -- The Rose Bowl Parade stepped off in Pasadena, California Monday morning.

For the past week volunteers have been putting in long hours to create the spectacular floats. The parade was 5.5 miles long and the theme is "Echoes of Success."

The grand marshals for the parade were Olympic gold medalists: runner Allyson Felix, diver Greg Louganis and swimmer Janet Evans.
