Looks like we need some more caches in the downtown Sacramento area, so I hid this one.
Solve the puzzle to find the coords:
N38 34.ABC W121 29.DEF
A = Alley between E and F plus one.
B = Alley between N and O.
C = Alley between F and G minus two.
D = Alley between K and L minus Alley between F and G.
E = Alley (path) between O and P.
F = Alley between S and T minus Alley between U and V.
