An army of volunteers woke before dawn this Wednesday and Thursday to go out to survey Santa Barbara County’s homeless as part a biannual Vulnerability Index to determine who is in most need of help and how resources should be divvied up. During the last count in 2013, 1,466 homeless people were encountered, 1,111 were interviewed, and 886 were deemed “vulnerable.” Above, volunteer Hannah Rael uses a new survey app to interview a woman living in her RV on Cliff Drive.
