This bell may be hard to notice because it's so close to a tree. It's more noticable in Winter, when the tree has shed it's leaves, but after Spring, the leaves of the tree start to obscure the bell.
As you're traveling Northbound (NW) on Monterey Highway, look to the right after you pass Branham Lane for this bell. If you pass Valleyhaven Way, you've gone too far!
This bell can also be seen in Google Street View.
