Hiro was our guide - great guy. He was very nice, and very knowledgable. The sandwiches he made were vegan friendly and tasty. We saw the sunset at the summit and observed the stars and milky way from just below, around 12,000 ft. He provided a detailed discussion of the constellations, and we enjoyed green tea (or hot cocoa) right after looking through the telescope at the Pleiades nebula. The drive was comfy in the van (9 people on our tour), and he provided winter parkas so we were warm at the summit (he also had snow pants for those who needed more warmth). We also got nice photos of us with the stars using a long-exposure camera. Overall a top notch trip.
