Yeah, idiots always mess it up for everyone else. Perfect example are the mine closures. We've been seeing pallets of what we thought were cement bags outside of mines west of Goodsprings. They've been emptying these bags in the mines and using long hoses, flooding the mines.
We went back over a month later to the same mines and found the floors were covered with about 10 inches thick of a grey, jello pudding-like mess. I'm not a fan of seeing bars over mines, but I would prefer to see bars than to see them destroy history like that. I wish I took pictures of the bags on the pallets so I could research it a little.
