This cache is located at the best possible location near the Bank of America. Even though this cache is near the bank, it is only accessible from the nearby offices. My best advice is to come during a time that is not high traffic for the offices (i.e. Later Afternoon M-F or Sat. Sun.).
Please use discretion due to the high amount of muggle traffic because of the offices nearby. This area is a very friendly area of Los Altos called Loyola Corners. It is one of the few parts of the city that businesses are allowed to function. There are not many residences in this area, needless to say that that the cache is most certainly not past any of the fences.
You don't have to bring a pen. As always, please put the cache back to its original location. Have Fun! Congratulations to Psychoticjester for the FTF!
