My best friend for 50 years and I had such a wonderful tour with Doc! I am a plant geek, and I had a million questions about the plants, animals, geology and history. Doc was so knowledgeable and entertaining, and he answered all of my (very many!) questions. He even found me a piece of fossilized sea sponge to take home! We really loved our morning. We both agreed this was the highlight of our trip. Thank you so much! I'll request Doc on my next Sedona trip!
