But the 826 Valencia store only scratches the surface of this non-profit's mission -- to support children with their writing skills and to help teachers get their students excited about the writing. Dave Eggers, local writer, was one of the founders of 826 Valencia, and its impact has spread nationwide. While at the store, I picked up a copy of Seeing Through the Fog: A Gateway to San Francisco, which is one of the projects to come out of 826 Valencia last year. It is a tour guide of San Francisco of sorts, written by 72 seniors of Gateway High School. Essays cover a wide spectrum of the city.
