That is how I felt when I first started caching. I Thought it was disrespectful to look for caches in cemeteries. But it wasn't long before I changed my mind and of course I am now hiding geocaches in cemeteries.
Of course, be careful, and do not destroy anything looking for this. It is an easy find with minimal impact if you remember to move only one or two things to find the cache.
while you are here take a moment to remember those loved ones who are no longer with us.
