Attendees tour with a guide to hear 10-minute presentations and converse with each of the 'spirits.'

This year's theme is, 'Women Who Left Their Mark.” Among those featured are Sarah Chase Bourn, matriarch of a prominent local family, who managed hundreds of acres of vineyard; Lola Grace Mackinder, who published the St. Helena Star newspaper; and Ivy Loeber, a local historian who helped found the Napa County Historical Society.

Tours leave at 1:30, 2 and 2:30 p.m. from the entrance
gate at Spring and Chardonnay streets. In case of rain, the event moves
indoors.
