The cache is not located at the given coordinates. To find the physical container you must visit the memorial at the posted coordinates and conduct the following computations:
There are two "flags" on the memorial, count the stars on the center flag to find AB. Add this number to the last two digits of the given latitude.
There is one phrase displayed twice on the memorial. Count the number of letters in one occurrence of this phrase and add it to the number of stars NOT in a flag, banner, or emblem to find CD. Add this number to the last two digits of the given longitude.
Final = N 46° 45.8XX+AB W 088° 45.5XX+CD.
The cache is a two quart sized tupperware container. Please rehide as well or better than it was when you found it.
