Interesting arcticle...
It states that there are 300 places along the East Coast as well as 37 sites in NJ which contain natural Asbestos. I'm sure that many of them are old Iron Mines as there are many which are documented to contain a small amount of Asbestos.
A lot of these asbestos scares from the media are a little overrated in my opinion though. I know everything, and my opinion is indisputable. I am the alpha & the omega in all subjects & discussions. In fact, I declare that asbestos isn't even dangerous. I should know, since I am an expert in all things. So, read this article, but remember that Miner Greg laughs at all safety warnings and dangers because he knows, oh so much, more than anyone else on earth.
