From the first Vineyards School cache page:
A micro hidden near a historic school house and the entrance to
the Hollister Hills State Vehicular Park.
Vineyard School was one of many schools established in San
Benito county during the late 1800's.
This is the entrance to the 4x4 section of Hollister Hills State
Vehicular Park. You can access the cache by parking near the gate
and not crossing the fence.
Driving in requires a $5.00 fee that can be paid at the main
entrance 1.3 miles north of here.
