People across the country are taking part in a national day of service marking the anniversary of the Sept. 11, 2001 terror attacks. The effort kicked off Wednesday in Manhattan where thousands of volunteers began assembling more than two million meals for needy New Yorkers aboard the USS Intrepid. Organizers say the effort is among at least 25 large-scale volunteer service projects taking place in cities across the country. Overall, about 30 million Americans are expected to participate in the service day, which is meant to serve as a counterpoint to the attacks that killed nearly 3,000 people.
