This cache is part of the WERDAVE 80 for 80 series celebrating WERDAVE's birthday and his extensive contributions to cache hiding, especially on the trails and in the parks around the Santa Clara Valley.
You're looking for a nano, naturally. The cache is at the Hicks Road entrance to Santa Rosa Open Space, which is a cool little preserve tucked in between neighborhoods in Los Gatos. The sign is fractured like glass, but it's perfectly legible and functional. I'm not exactly sure where the park borders are, so I'm going to assume the cache is accessible only during park hours of 7am to sunset.
You can't park directly in front of the trail entrance, but there's legal street parking within 100 feet. Happy hunting!
