Audrey, I love all your photos! I never thought of creosote being a plant.........thought it was a chemical preservative for wood. The crest on the saguaro is so cool! I love the story about the Castle hot springs resort too. Was there a hot spring? I've swum in a hot spring pool in the Rock Mountains in Canada.......the air was icy cold and the pool was so deliciously warm.
I love all this dialogue back and forth.....great to learn about other areas of the world.
