After Marathon we made our way to the Mcdonald’s Observatory. We climbed close to 2,000 ft. Biggest hill ever. We stocked up on food because the observatory was extremely remote, so our bags were good and heavy for the epic uphill. We also bought a bottle of wine, brie cheese and crackers in Fort Davis (the town at the base of the mountain) for our hosts as a nice gesture. Our host John, is one of the main astronomers at the observatory. Once he let us into his home, he drove us straight up to the observatory and took us to the catwalk atop of the telescope so that we could see the sunset. There was a 360 degree view of the surrounding plains and mountains. Truly breathtaking. No one for miles! He gave us a run-down about the telescope as well. We spent the next day checking out the observatory and even got to see the sunset from the catwalk of the other massive telescope. There was a full moon too. Just no words. Stunning scenery, a definite high point of the trip. It made the two hours of ascension up the mountain all worth it!
