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.
The cache is hidden on the Limekiln Trail in Lexington Reservoir County Park, just before the trail enters Sierra Azul OSP. As the cache name suggests, you're looking for a spot where an oak shrub, a cherry plum tree, and a small bay tree are hanging out just over the edge of a small clearing. The cache is a small decon container tethered to the oak part of this trio. It's low enough that it shouldn't be visible from the trail, but it should be visible when you get close enough.
Lexington Reservoir County Park is open 8:00 a.m. to sunset. Happy hunting!
