PEOPLE PERSON: Isabelle T. Walker has spent the past three years writing and reporting about the homeless in Santa Barbara, both for The Independent and for her own blog. She’s observed how the recent survey of homeless people came to pass in the first place, and was there when about 500 volunteers got trained in how to wake people up—at 4 in the morning—who might otherwise prefer to be left alone, to ask how they got on the streets, how long they’ve been there, and what it might take to get them off the streets. Walker used to report on health-care issues but quickly discovered how frequently the two issues intersect. When she’s not writing for The Indy, she’s writing for HomelessinSB.org, thanks to a grant from USC’s Annenberg School for Communication, not to mention the McCune Foundation and the Fund for Santa Barbara.
