This is a very well maintained hilltop cemetery.
Near the entrance you will see a flagpole that was erected by the Barnes brothers and dedicated to all armed forces veterans buried in the cemetery. Evidently six of those veterans were Barnes.
You needn't trouble yourself to read the hint. I am confident that, if you've been caching for more than a week or two, as you drive up the hill you will behold the hiding spot. You'll be looking for a small white cylinder- like thingy 1.5" tall and 1" in diameter.
