Abe Cyphers


“Sonoma has changed quite a bit from when I grew up here in the 70’s. I remember the town was filled with fields and orchards and when they poured the pavement for the shopping center on 2nd St. West my friends and I couldn’t believe that there was that much asphalt in one place – it was skateboard heaven! Things have changed quite a bit since then with Sonoma becoming a much sought after destination city, but one thing that hasn’t is the natural beauty that surrounds the Valley. Kids today can still find a field to play in, or a creek to find frogs in. Now there’s even a skatepark to skate in instead of an expansive parking lot. Even with the growth that the Valley has seen I think you will still appreciate the small town feeling that Sonoma evokes.”
