Photos: Honoring workers, enjoying ‘final’ hours of summer on Labor Day in Sonoma County

Labor Day in Sonoma County was marked by warm, sunny weather — though the marine layer brought its typical moist cover in the morning hours.

Once the clouds cleared, people jaunted outdoors to soak in the final hours of the summer season, and to honor local workers.
