    I was impressed with Dr. Todd Bostwick's presentation. I am not crazy living this far south in Phoenix, but now that I live in South Mountain, I was surprised and thrilled to learn that there is any, let alone so much rock art in this area. Makes me want to explore more. Thank you Sierra Club for making this event happen!

    What a wonderful evening! Thank you, SC, and Dr. Todd Bostwick. I will have to be more observant now on my Geronimo - Mormon Loop likes. Hmm. Wonder what animal(s) I will dream about tonight?
