I was just up there last week, talking with the rangers at the Mono Lake station. Even that short of a time ago, they were estimating a mid-July opening, so this is a pleasant development. There's still ice on many of the lakes up along that route, and big ole snow banks on each side of the cleared road up to the entrance station to Yosemite.
One day I'd like to hike the entire John Muir Trail and not leave a single footprint. -Randy Morgenson
