Sukkot is the week-long harvest festival when Jewish households build and eat in a sukkah. In SLO County that means outdoor meals, a communal sukkah at the synagogue or Chabad house, lulav and etrog shaking, and open sukkah nights that anyone can drop into. The middle days are informal, so this is the easiest Jewish holiday to join without a ticket.
