Warm during the day and then the fog rolls around! Bring a jacket/sweater, maybe some extra layers. There will be some inside seating/area, and a few heat lamps.
Because this whole event got postponed and then was a maybe up until a few weeks ago... we didn't book any hotels. We have several guest rooms available through family and friends, so if you are desperate please reach out and we will try to house you! Otherwise, hotels in Petaluma, Sebastopol, or Rohnert Park/Cotati will be the closest.
