 And I didn't know this, so I tell people that when we're looking. I tell them they're plentiful and they're in the earth. And they're like, well, how do you find them? I said, you can find them inland because it was all over ocean. These are millions of years old. They're fossils. I said, I thought they were white. Well, they're white. I looked this up on the way home yesterday. It takes over 10,000 years for it to start turning gray and black. Wow.
