This is a active, well-maintained cemetery not far from Bigelow. The cache is near a road which is busy at times, and since there are often people in the cemetery, stealth may be required. Though not a PNG, this one sholdn't be very hard to find.
You are looking for pill bottle hidden in a traditional way, and it is not on or near any grave. Though you can park near GZ, take a few moments to browse interesting headstones, and practice CITO should you encounter any trash. No night hunting, and always respect the residents and those who may be visiting them. Put the cache back as you found it so others will enjoy the hunt also.
Should you find any problems with the cache, please let me know.
