PRESTON: There are now close to 800 food pantries on college campuses. A decade ago, there were just 80. UC Davis was one of the first to open up its pantry, buried in the basement. Now the pantry is at the heart of the campus. It's not intended for those with a meal plan or who can afford groceries, but it's open to anyone with a student ID, no questions asked.
