This fun puzzle cache adapted from the original GC1BF0T in MD.
The posted coordinates are for the Post Office. The cache is NOT in or next to 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 this set of three numbers for the cache. (Grid:Row:Column)
Grid:
When you enter the Post Office you will find multiple walls with post office boxes. A normal group of boxes is about 5 feet tall by 2 feet wide and a wall may have from one group of boxes to many groups of boxes. The Grid refers to a group of boxes on any particular wall that is outlined in black trim.
The Grid number is determined by the number of the P.O. Box in the upper right-hand corner of the Grid. Find the P.O. Box number that matches the Grid number and you are standing in front of the Grid you need to use.
A Grid has rows of boxes that run from left to right and columns that run from top to bottom. The P.O. Boxes at the bottom of the grid are usually bigger than the boxes at the top. The rows will normally lineup across the entire grid, but the columns will not. There will be more columns on the top of the Grid and less along the bottom of the Grid.
Row:
Starting at the upper left corner of the Grid and counting from top to bottom, the top Row is 1 the next Row down is 2 and continuing on to the bottom of the Grid.
Column:
Counting from left to right, the leftmost box is Column 1 and the next box from the left is Column 2 and continuing on to the right of the Grid. Warning! Row 1 will probably have more Columns than Row 9, so be sure to be counting across in the correct row (That is why the Row number is before the Column number).
All that is left is to plug in the P.O. Box number that is at that particular spot on the Grid into the cache coordinate.
To find the cache location, use the (Grid:Row:Column) format.
34.(G61:R6:C3)(G241:R9:C2), -82.(G1:R4:C2)(G61:R5:C2)
Final coordinates will be in the 34.XXXXX, -82.XXXXX format.

The P.O. Box lobby is open 24 hours.
The final cache location can be a high muggle area, so use stealth and BYOP.
