Old Texas Cemetery is well-maintained cemetery just north of Hwy 25 in rural Faulkner County about three miles east of Guy.
You are looking for a camo bison tube hidden in a fairly traditional way, and the cache is not on or near any grave. This should not be too hard to find, but the coordinates bounced a lot during cache placement, so I've bumped up the difficulty rating a bit and added extra detail in the hint.
On your walk to GZ from the cemetery entrance, take a few moments to walk around and browse interesting headstones, 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.
