Wearing bright colors, Elva Treviño Hart stood before hundreds of students in the Huntington Beach High School gym and described what it was like to feel invisible.
Hart, the author of the memoir "Barefoot Heart," said an interviewer asked her about that feeling the first time she appeared on the radio to promote her book. The invisibility in question was that of migrant farm workers, and to illustrate her point for the students, Hart laid out a table with ketchup, pickles, berries and other supermarket produce.
Each piece of fruit, she noted, probably came from the hand of a worker who had a temporary home and a family to feed. Hart, the daughter of a migrant family, said she often observed pickers in the fields near her home in Virginia, and she found the situation hadn't changed.
"Each orange requires a hand, a human hand, to get it off a tree," she said during her recent visit to the school. "They're experimenting with electronic pickers, but it really requires a hand."
