Welcome to Glenwood Park, one of Atlanta's newest neighborhoods.
Like Atlantic Station, Glenwood Park is a planned community built on an old brownfield site. Quite a few movies and commercials have been filmed here. As of this writing, it is also home to one of the Real Housewives of Atlanta, and she is often spotted around here with camera crews.
At the posted coordinates, you will come to an object that has been here since soon after the founding of Glenwood Park. As an aside, across the street you will see a coffee shop where a scene from the movie Hall Pass was filmed.
There is a round sign posted on the object. What is the four digit number on the sign? This number = ABCD
Stage 2:
N 33 44.(AB+402)
W 084 21.(CD+494)
At stage 2, you will be in front of a restaurant where a scene from the movie The Blind Side was filmed. What time does the restaurant open on Tuesdays? Turn this into a three digit number, EFG.
Final:
N 33 44.(E-1)(G+1)(Fx2)
W 084 21.(F+1)(A)(Dx3)
Due to high muggle activity, this is a standard hide that you should be able to find easily and inconspicuously.
Edit: It seems the Real Housewife no longer lives in the area. Some other things filmed here since this cache was published:
The Boss
Pitch Perfect 3
