Anyone been to Yosemite up Tioga Pass Rd or Tuolumne Meadows in the past few days, and can comment on the conditions? I'm planning to hike the Grand Canyon of the Tuolumne (White Wolf to Tuolumne Meadows) beginning on Friday, and wondering whether I'll be affected by smoke from the Meadow Fire near Little Yosemite Valley.

Barely related question: is it possible to pick up previously-reserved camping permits somewhere in Tuolumne Meadows, or do I have to go to the office in Yosemite Valley?
