The comments here say it all.
Apparently 950 acres isn't enough for the feel goody theme park the National Parks Service intends to create. 500 more acres is needed. At the point of a gun.
I am all in favor of a tasteful memorial for those brave people aboard the plane. But nothing about this seems tasteful- more like a land grab by the National Parks Service. Naturally they'll need a slightly larger budget, more people employed, etc, etc.
