I was in the Leavenworth/Wenatchee area over the weekend up high. Even the areas that are open are so covered in smoke that the back of your throat burns and visibility is at most a mile. At least it is near 1/4 mile. I would highly advise avoiding anything over that way. It isn't healthy and doesn't feel good on the lungs. Up at ~7000 feet it wasn't as bad, but still not great. The poor air quality starts about Gold Bar and gets worse from there on HWY 2.
