The P.R.C. stands for Peaceful Rest Cache. Yes, they are near or in cemeteries so you must abide by a few rules. No hunting these caches after dark. That is a state law on being in a cemetery when it's dark out. The second is dogs. Not all have rules on dogs being in them, but let's show some respect. We don't want Fido peeing on Uncle Joe. These are meant to take you to a few of the out of the way places. I myself enjoy reading the old stones.
Parking is on the same side of the road as the cemetery. Pull all the way off and watch for traffic. The container is a large screw-top container with a smaller one holding the log. Room for very small items only. Be sure to secure the gate when you leave.
