KINGSTON — Weather forecasters are predicting sunny skies for Saturday, which Naomi Maasberg is happy about.

The administrative director for Stillwaters Environmental Education Center has more than 30 vendors coming to set up camp on the organization’s property Saturday during the nonprofit’s annual Earth Day event, EcoFest. Each will be loaded with information about environmentally-friendly resources, such as rain barrels, “green” building materials and biodiesel vehicles.

“The owner is bringing (his car) which is great because they can talk about it because they actually use it,” Maasberg said.

There are several new performance groups added to the entertainment line up this year, including the Poulsbo Sons of Norway Dancers, Hansville’s Boot Scootin’ Grannies and students from West Sound Taekwondo.

The event has grown since its inception in 2000 and Maasberg believes its success can be attributed to the fact that it’s a great family event where people can get their environmental questions answered on anything from noxious weeds and septic tanks to the importance of small streams and what’s going on with local parks and green space projects.

“I think what’s successful is it’s a fun event,” she said. “There is a lot of good information people go for (too).”

But Stillwaters won’t be the only place hopping with Earth Day events — the Kingston Farmers Market will be opening for the season, Kingston Revitalization Association will be hosting an art walk, the Friends of the Kingston Library will be holding a book sale and the Kingston Art Gallery will be hosting a community art project.

Friends of the Kingston Library member Marilyn Olds said approximately 5,000 used books will be for sale at the Kingston Community Center, noting that the proceeds will go toward building a new library.

“We’ve got millions to go, quite literally,” she said with a laugh.

KRA will be hosting the art walk throughout downtown Kingston. Last year’s walk was a big enough success that the Kingston Art Gallery was formed, said KRA member and Kingston Chamber of Commerce Executive Director Sally Christy.

Besides the artists in the gallery, eight others will be displaying their works around town at different retailers. At the gallery, there will be an ongoing art project during which visitors can create paving stones that will be installed at the gallery. There will also be a raffle for five pieces of art, which will be raffled off at 4 p.m. Raffle tickets can be purchased this week between 10 a.m. and 2 p.m. at the Kingston Chamber of Commerce office in the community center or at The Coffee Exchange.

“It’s just a good way to get involved in the community,” Christy said of having artists and businesses work together.
