Nonprofits across the United States are gearing up for service projects for volunteers who want to give their time to charity to help mark the 10th anniversary of the September 2001 terrorist attacks.

HandsOn Greater D.C. Cares, in Washington, plans to enlist more than 10,000 volunteers to participate in a wide range of service projects throughout the metropolitan area on September 9, 10, and 11.

A small group of volunteers is getting ready now for the September service projects. Many of them gathered recently at the organization’s massive tool shed, for instance, to make sure its hundreds of hammers, drills, and shovels are ready for volunteers who will refurbish schools and work on neighborhood-improvement projects.

See this video to learn more about how this small group is preparing for the big event. And if your organization is planning its own day of service, please let us know how you’re preparing by posting a comment below.
