If you've been looking for a way to introduce volunteering to your grandchildren, next Saturday might be the day. Just as he did before his first swearing-in, President Barack Obama is asking Americans to participate in a National Day of Service. Four years ago, President Obama's day of service coincided with Martin Luther King Day, which was designated a day of service by Congress in 1994. This year, the public inauguration will occur on MLK Day, thus the shift to Saturday.
President Obama has been a big booster of roll-up-the-shirt-sleeves volunteerism. During his first term, Sept. 11 was designated as a day of service and remembrance, and the President also established a National Volunteer Week in April. He and family members have volunteered at construction projects and soup kitchens.
