LOS ANGELES -- The American Red Cross and mail service provider Pitney Bowes Inc. are asking people to help them send a lot of holiday cheer to U.S. troops this year.

The organizations have launched a program called Holiday Mail for Heroes. Organizers are hoping to collect at least a million holiday cards to send to soldiers and wounded troops both at home and overseas.

Even First Lady Laura Bush has gotten in on the action, showing up at a Red Cross center in Washington, D.C., where she helped make a few cards.

"It was very sweet to sort and read these cards and see what Americans have written in to our troops," said Bush, who encouraged volunteerism throughout the holidays. Volunteering is"really an important part of the holiday season," the First Lady said.

Red Cross officers across the country are collecting cards. People can make their own cards or download one. Visit the Red Cross Web site to participate.
