Just bringing this thought to mind not all cachers are "good" and not all cachers are "bad" but they can be very destructive, take GreenBelt view for instance that palm tree. then there is the note about the out of gas cache, I think that the cache owner needs to keep in mind that cachers are not perfect and destruction can be had either by accident or purpose it goes to the thought of that looks like a great place for a cache BUT is a cache great for the place???? sister cities comes to mind......
