The San Francisco East Bay graticule is at latitude 37, longitude -121. It covers the area east of Oakland and Berkeley, including Livermore and Tracy, and also includes San Jose. This graticule makes for a good fallback adventure when the San Francisco, California graticule's geohash is in the water, as often happens.
