This cache series is being extended and was originally developed by Maryland cacher mdsurveyor. With his kind permission and help, I am continuing the concept. The posted coordinates are for the Post Office. The cache is NOT in or next to the building. However, a clue will found on the building. The cache will be within walking distance or only a short drive from the Post Office. A simple puzzle once you learn how to apply the sets of three numbers for the cache and some simple math, using the (Grid:Row:Column) format: N 42° [(00.088) + (G2230:R4:C11) + (G2290:R5:C5)(2) + (G2290:R3:C5) - (G2290:R2:C3) + (G2230:R1:C1)/(2)] W 076° [(38.028) + (G2230:R4:C18)(3) - (Sum of “ZIP + 4” numbers)(40 - 1) + (G2230:R3:C5)(3)]
The lobby is open M-F 9:00AM to 5:00PM and Sat 9:00AM to 12:00PM, and closed from 1:30PM to 2:30PM M-F, thus increasing the difficulity.
If this is your first "P.O. Box" cache, visit the first in the series, P.O. Box – Bel Air (GC1BF0T), for the instructions to help you solve the puzzle.
BYOP.
The Geosum (the sum oF ALL numbers) of N is 28 and of W is 34.
Congrats to Gardenguru for FTF!
