I was out finding some "unworthy caches" and it seemed like a good opportunity to hde another cache for others to find. I am unsure of the parking here, as there were signs before the structure here, but none after. My best guess is that it's ok, but if you're unsure there is parking near one of the nearby unworthy caches (GC51CXV) if you want to park and walk.
The cache is at or nearby the coordinates listed. I didn't have my GPSr with me, so I used my phone and corrected as best I could with Google Earth. Please leave out any hints, pictures or outright revealing information from your logs, as apparently some like to do this. Also, please do not "improve" the hide, if you please. I am not giving the size, but one could infer from the lack of a writing stick that it's smaller than a pencil.
I noticed a sign for Yerba Buena school nearby, and curiously searched for the meaning of the name on the web. Wikipedia has this to say, and upon reflection, I didn't see any nearby.
Yerba buena or hierba buena is a name of Spanish origin used for a number of aromatic plants, most of which belong to the mint family. The Spanish name yerba buena translates as "good herb". The specific plant species regarded as yerba buena varies from region to region, depending on what grows wild in the surrounding landscape, or which species is customarily grown in local gardens. Perhaps the most common variation of this plant is spearmint (Mentha spicata). The term has been (and is currently) used to cover a number of aromatic true mints and mint relatives of the genera Satureja or Micromeria. All plants so named have medicinal properties, and some have culinary value as herbal teas or seasonings as well.
Good luck and enjoy!
Have fun!
