SAN DIEGO — Frank Kensaku Saragosa felt a bit uneasy as he walked past the tents that lined the sidewalk along downtown San Diego's East Village.
"I used to stay over there," he said, pointing to an embankment off Commercial Street near Interstate 5.
Saragosa, 56, was anxious that some of the homeless people in the sidewalk encampments might recognize him from the four years he spent on the street.
