I came to the City of Rocks and Castle Rocks for the month of May to volunteer with little understanding about what I would do except give tours of some sort. I had driven through the area about ten years ago and liked it. After a quick phone call and a check of my references, I was hired for the volunteer gig. I was sure all would turn out and it would be a happy month. How could it not be happy? I was going to where rocks are 2.5 billion years old.
