ARLINGTON — The winter holidays might be done, but the organizers of this year’s Arlington Relay For Life plan to inject some evening sparkle into the first month of the New Year.

The Magic Kingdom will be coming to downtown Arlington on Saturday, Jan. 21, at 4:30 p.m., as the Arlington Relay For Life kicks off its third year with a Disney-themed “Parade of Lights” on Olympic Avenue.

Mickey Mouse will head up the parade as grand marshal, and he’ll be joined in the parade by fellow Disney characters Cinderella and Snow White, among others.

An assortment of lighted vehicles, the Rotary train and a decorated fire truck will round out the parade lineup.

The parade will precede the official kickoff of the 2012 Arlington Relay For Life season at 5 p.m. at Presidents Elementary.

This year’s Relay is planned around the American Cancer Society’s theme of “The Magic of Relay — Dream It, Hope It, Cure It.”

The Arlington Relay itself will run from Saturday, June 23, at 1 p.m. through Sunday, June 24, at 9:30 a.m. at Arlington High School’s John Larson Stadium.

Last year’s Relay raised almost $300,000 for the American Cancer Society.
