Our car entered the Yosemite National Park along the No. 41 highway in California. In the long Wawona tunnel, the wall was lit by the dim yellow light. The water drops from the top of the tunnel gathered on the road surface, reflecting the tail lights of the cars ahead. Everyone in the car was very quiet. Yosemite National Park is undoubtedly a holy place for photography enthusiasts. It's where photography master Ansel Adams lived and took photos all his life.
