Look for the above plaque which reads "Foothill College Bridge..." with the name "Bob Stutz" on one of the posts. If the name sounds familiar, he is the Mr. Stutz of GCK97T, Los Altos Hills Pathways: Mary Stutz Path.
There are at least two ways to approach the area. One is off a dead-end residential street, and the other is at the end of a parking lot. Even without a mapping function, you should be able to find them by following the GPSr to the posted coordinates. Please rehide the cache in the same location.
Note: To avoid poison oak, start your search on the NW corner of the bridge.
