I love rock collecting. I enjoy rockhounding as its called in the United States.
That is a neat hobby. Where do you go to find your rocks?
I always find rocks in their natural environment.
I see. What is your favorite rock in your collection?
I really like  my ruby rock. I used a geologist hammer to get it.
Oh nice. Does it have a reddish color?
Yes, speaking of Ruby. Have you ever heard of Rock on Ruby the racehorse?
