It's a bunch of blind souls believing they're doing good, and have gotten this far because their agenda works hand in hand with the government one. Most of our provincial/state/national parks are resource rich, that's the only reason they're protected. Proof of that is whenever it's convenient for someone with campaign donation ties, the boundaries get moved to accommodate logging, mining, pipelines, or what have you.
There's 2 dates in time they'll carve on your stone, and everyone knows what they mean.
But what's more important is the time that is known, as that little dash there in between.
