Graveside Boondocking?

I'd like to know the opinion of others on this subject, as my co-workers and family have varying viewpoints. I see many post about boondocking. Some in very public parking areas such as Wal-Mart parking lots and some on the side of mountain road. Has anyone ever rested in the parking area of a rural cemetery or graveyard? I've seen several back country graveyards in my travels and some of them seem like a quiet out-of-sight place to rest for a night. Most have signs posted indicating hours are from daylight to dark. But does that apply only to the fenced in grave sites or to the parking area as well? Now I'm not talking about setting up shop with generators and tiki torches. Just a brief stop and rest.
So if a person isn't spooked by the idea of the location, would it be considered disrespectful to the deceased or frowned on to occupy a parking spot for a night? In my neck of the woods lots of back roads country churches also have adjacent burial plots. When I ask, people seem fine with staying at that type of church parking lot. But for some reason people cringe when I say "now what if the church wasn't there?" Thoughts??
