Quoting from this site:
It is unclear how many students are spending spring break helping with the recovery effort. But nearly 700 students from 85 schools in 27 states will be on the Gulf Coast with Sen. John Edwards, D-N.C., this week alone. Thousands of others have been here in recent weeks, and more are expected between now and the Easter holiday.
Many of the trips have been organized by colleges, some of which are offering students credits for their labor. Others have been arranged by volunteers, churches and other charitable organizations, such as Habitat for Humanity.
Just when you thought God ought to wipe the planet and start over–you get a reminder that there are actual human beings out there.
