Welcome to Pumpkin Village (yes, that's its real name!) Cemetery. This quaint cemetery is home to many treasured Sheldon/Pumpkin Village residents; all of whom passed before the 20th Century. The trees here are quite reminiscent of The Holiday Forest; in a place almost akin to Halloween Town's Spiral Hill Graveyard.
To find the cache, you need not walk down an extended ramp hill to find GZ. Much like Jack Skellington, gently wander through the graveyard, and examine the trees.
BYOP; Stay Safe!
*Note: Park nearest you can to road and prepare to walk up a hill. Terrain may very depending on weather; may not be suitable for all vehicles.
