On the eve of his inauguration, President-elect Barack Obama marked the Martin Luther King Jr. holiday by spotlighting King's dedication to community service.
Obama, who has promised to make public service a theme of his presidency, made several stops throughout the day, beginning with a visit to wounded troops at Washington's Walter Reed Medical Center.
Next he visited an emergency shelter for homeless D.C. teenagers, where he picked up a paint roller to help a few dozen teens who were renovating the boy's dorm.
"We can't allow any idle hands. Everybody's got to be involved. Everybody's going to have to pitch in," said Obama at the Sasha Bruce House, accompanied by Martin Luther King III.
"Dr. Martin Luther King's was a life lived in loving service to others," Obama said in a statement early Monday. "As we honor that legacy, it's not a day just to pause and reflect - it's a day to act."

The president-elect told volunteers at a luncheon at Calvin Coolidge High School this afternoon that he was "making a commitment to you as your next president that we are going to make government work."
Still, on a holiday reserved to honor the strides of Dr. Martin Luther King Jr., Obama added, "Government can only do so much. And if we're just waiting around for somebody else to do it for us, if we're waiting around for somebody else to clean up the vacant lot or waiting for somebody else to get involved in tutoring a child, if we're waiting for somebody else to do something, it never gets done. We're going to have to take responsibility -- all of us."
As the former community organizer prepares to take the oath of office and asks people nationwide to commit to bettering their communities, public service professionals like Andy Nelson of Portland, Ore. suspect Obama's call to action may have given some people an extra push.
"Typically after the holiday break, we see a real drought in January in terms of volunteer numbers," Nelson, executive director of Hands On Greater Portland, told ABCNews.com. "This year, the phones have continued to ring and we are seeing a real spike in volunteering."
Indeed, the spirit of volunteerism may be contagious, according to Americans rolling up their sleeves and committing to service projects today on the day before Obama's inauguration.
In neighborhoods around the country, people were heading out to answer the call to serve.
Close to the White House, fire and EMS stations served as hubs for a food drive, with canned food being donated to the Capitol Area Food Bank in Washington, D.C.
In Portland, Hands On worked alongside nonprofit groups and schools on diverse projects that include painting a school, weatherizing homes and refurbishing donated bicycles for children. Nelson said the organizations were expecting more than 800 volunteers at 30 projects in the Portland metro area during the weekend and Monday.
In central Ohio, Planned Parenthood volunteers collected women's essentials at a week-long drive organized to provide necessities to a Columbus shelter for women and families in need.
