Hot? Who says it’s hot?

Saturday’s high temperatures did not dampen the enthusiasm of volunteer artists at La Strada dell’Arte, the annual street art festival at Copia, a fundraiser for New Technology High School.

As a volunteer paced back and forth to distribute water bottles, about 250 students of all ages, parents, grandparents and other artists who signed up for the fourth annual La Strada dell’Arte drew chalk images as visitors strolled by to chat with the artists or take pictures of their work.

Susan Lane, director of development at New Technology Foundation said this year’s goal is to raise $130,000 in cash and in-kind donations for the 400-student high school.

Victoria Wallace, a student at New Technology High School, was among the teens who spent their afternoon transforming the pavement into a multi-colored palette.

“It’s a little hot, but it’s fun,” said Victoria, as she worked on a sci-fi rendition of a countryside.

Others drew their inspiration from other artists, American Indian folk tales, or their own imagination.

Sam Bartos, a New Technology High School senior who wants to major in broadcasting and communications at San Francisco State University next year, sketched John Lennon. Nearby, Jordan Slavens, a fellow schoolmate, copied a picture of a Samurai downloaded from the Internet.

“I thought it was cool, so I said ‘what the heck, I’ll do that,’” said the 15-year-old.

Charles Funk of Chehalis, Wash., who came at the request of his granddaughter, Brittany Bonneau, 16, a student at New Technology High School, who drew a witch from a folk tale from the Chinook tribe.

Morgan Lee, another New Technology High School student, said she volunteered Saturday, because she did not want to miss out on the experience. She will change schools next year, she said.

Lisa Davis, her two children and friends, were among the vistors who checked out the art, including the sketch drawn by her younger sister, Raven.

“It’s so neat,” Davis said as they ate lunch. “They work really hard,” she added.

This year’s featured artist, Cecelia Linayao, an artist based in San Diego began to work on her project on Friday, a 12-by-12 foot sketch of a young girl — her niece — reaching out to a computer keyboard to acknowledge New Technology High School’s high-tech programs.

She planned to draw an old-fashioned painting frame around the sketch to created a melding of “the old and the new.”

Linayao said the past few days were eventful.

Earlier in the week, Linayao was in Xian, China, to work on a public art project, when the earthquake struck while she visited a historic tower. She flew home on Thursday, she said.

By Friday, the artist was in Napa, ready to begin her sketch, oblivious to the time difference between the United  States and China.

“It’s very much an honor to be featured here in Napa,” she said.

Many of the artists said they expect to complete their work on Sunday. Lane expected up to 7,000 visitors during the weekend event.
