The cache is not at the posted coordinates.
This is the bonus cache for the East Village Arts and Culture Adventure Cache. To solve the puzzle, you'll take the clues you'll find in the five completed journal entries and render them as follows:
N 51° 02.ABC W 114° 02.DCE.
Bring your own pen or pencil.
Congratulations to sapien on the FTF and first to complete the associated adventure cache!
