Bob, thank you so much for all of the time you spent emailing us back-and-forth and giving us all the information we needed to come prepared to climb. My husband and I were delighted to be challenged by the climb up to the climb and the climb down from the climb. We can brag to our friends that we also climbed! Especially nice to have Drew, our grandson offer his hand to me helping me climb down. He is a real gentleman. We were impressed by the way you interacted with Drew. You were clear, specific, and encouraging. You are an excellent teacher.
