Well when I die, and if I have a tombstone, which I won't, I'll be cremated, but if I did, I'd make a kickass tombstone, and have it say "May he who loves to vault, vault over me." I disagree with cemeteries, they really are a big waste of ground that could be used for much better purposes, especially here on an island, in Hawaii, where real estate is extreme. All for some rotting bodies that do not even represent the person that they once were.
I'm with Ozzi that I think it's throwing a rock at the wrong bird, if you will, going to a cemetery for your loved ones. They aren't there, I promise. Their tombstone is a stone, and the words were made by some guy who makes words like that every day, and have no meaning to him. If you really want a physical representation, how about something smaller than an 8 by 4 foot square of good earth?
If I was dead there, I'd be grateful that somebody is using the damn ground for something useful.
This is of course my opinion, which is a minority of an opinion, and so these kids were not smart in doing what they did for obvious reasons, that it offends people, but I think both the people and some traceurs are coming down a bit hard on them. After all, they are just kids trying to have fun in the best way they see fit. Bad decision? Yes of course. I don't mean to defend them, I wouldn't and have not trained in a graveyard, but people walk their dogs and let their pets go pee and what not in graveyards all the time. I know, I lived by one. If a dog peeing on your Uncle is less disrespectful than some kids doing athletic training, then I've got some things to learn.
