You aren't collecting fingers, you're collecting numbers----coordinate numbers. Your coordinates will be:
N 38 3A.BCD. W 121 4E.FGH.
Park at the parking coordinates and walk to the posted coordinates. There you will see a big, green electrical box (sometimes called a "gator") with a 5-digit number. Counting left to right, digits 1 and 3 are F and G.
Walk west-ish along the sidewalk. Shortly you will come to a second box with a 4-digit number. Digit 1 is B.
Keep walking in the same direction. There's a box behind a fence with a 5-digit number. You want the third digit; it is C.
Look across the street. There is another gator box, and you can see the 5-digit number from where you are. The second digit is A and the last digit is D.
Keep walkiing forward along the sidewalk (more or less west). This is a longer walk, so be patient. You'll come to a small green box with only one number on it. That's both E and H.
Now you have your coordinates! Container is a micro, but not a nano.
Because of the wandering coordinates, I have added a big, broad hint. It should help a lot!
