Plumerville Cemetery is a large, well-maintained cemetery in Conway County near Plumerville.
You are looking for camo bison tube hidden in a traditional way in a very familiar hiding spot, and the cache is not on or near any grave. It's at the very top of the hill and shouldn't be too hard to find. Though you can't park right at GZ, take a few moments to browse interesting headstones during the short trek up the hill. And practice CITO should you encounter any trash.
Remember that this is Arkansas, and you could potentially come across various critters and plants, some dangerous, so be careful.
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.
