This cache is not at the posted coordinates. You will need to go there to obtain the final location.
At the coordinates, you will be at a house (246 Neptune Ave), and on the left side of the driveway looking from the sidewalk will be a plaque. Note: there is no need to go onto private property or even leave the sidewalk to view this plaque. The plaque has some information about The Eagles, which you may find interesting. Use the plaque to solve for the final coordinates.
A = The number of white flowers on the plaque
B = The number of red flowers on the plaque plus 1
C = Third digit in the year on the plaque plus 2
D = The number of white flowers on the plaque minus 2
The coordinates are the following:
N 33 03.AB0 W 117 17.C0D
You can validate your puzzle solution with certitude.
