A proposal for a new downtown Petaluma winery, tasting room and auto racing museum is gaining momentum. Adobe Roads Winery CEO and racing luminary Kevin Buckler says he’s just weeks away from securing the six-million dollars in investor funding to support the riverfront facility at the corner of First and C streets. Once city officials approve the proposal, the project is expected to take about ten months to build and could be open as soon as the end of next year. Buckler anticipates hiring as many as ten new employees.
