The theme is conserving water during a drought. The fair organizers have asked each of the 30 exhibitors to come up with a question on how their exhibit relates to water conservation, said Brandi de Garmeaux, Portola Valley's sustainability and special projects manager.
For example, exhibitors promoting LED lamps could pose a question for which the answer could be how LED lamps lower demand on the electrical grid, thus lowering demand at a water-driven power station. An exhibit on enjoying open space could ask about the effect of the drought on tick populations.
Visitors to the fair will be given "passports" listing the exhibitors' questions. The passports will be stamped at each exhibit. Enough stamps and the visitors participate in a raffle.
The questions are meant to engage people of all ages, and the drought is a perfect opportunity for that, Ms de Garmeaux said. "They're really hungry for what they can do beyond turning the water off when they're brushing their teeth," she said.
Food and drink
Visitors who ride bikes to the fair will be rewarded with $2 vouchers redeemable at either of the two food trucks: San Francisco-based Little Green Cyclo, with Asian dishes; and San Jose-based Grilled Cheese Bandits, which probably needs no elaboration. The first 100 visitors will receive food-truck vouchers.
Half Moon Bay Brewery, a green business, will provide alcoholic beverages. Fair visitors are encouraged to bring their own refillable water containers.
Wild animals need drinks, too, and the Paso Robles-based Conservation Ambassadors will be giving a presentation at 2:15 p.m., with real animals, that is expected to address wild-animal water needs.
A limited supply of compost will be available in bags from Green Waste Recovery Inc, the San Jose-based recycling and garbage handler for both towns. A free document-shredding service will be available for the day.
State Assemblyman Rich Gordon is expected to talk briefly at 2 p.m. about legislation to promote sustainability; following his talk will be a recognition by the Arbor Day Foundation of the town of Woodside as a "Tree City USA."
Live music will be by PJ Weston & the Unstable.
