I road Squaw pass yesterday and it was a great ride!
There was no gravel on the entire trip, however they are finally repaving the east side. They've got about 2 miles of fresh blacktop down and the rest is bumpy like it always was. I had to ride through a construction zone for a while, but some of it was wide open and smooth as silk.
Hopefully by the end of this year it will all be in good shape.
