Years ago, I visited my relatives in Texas and we went to Carlsbad caverns. Before we went in, we watched as a swarm of bats flew out of the cave. Watching those bats made me feel like Batman. When we went inside the caverns, I felt as though I was in a Jules Verne novel. All kinds of beautiful rock formations decorated the caves. It was like entering a primeval world that time forgot. If I turned around the next corner and found a prehistoric monster, I would not have been surprised. I am thinking of drawing inspiration from my experiences in Carlsbad for my future dinosaur books.
