One possibly good point about the severe lack of snow this year, Caltrans could open Highway 120, Tioga Pass much earlier than usual, maybe even right now. The Mono County Local Transportation Commission wrote a letter to Caltrans and Yosemite National Park with that request. The Mono Supervisors planned to talk about that at their meeting today.
