From
https://inciweb.nwcg.gov/ I see that there are two fires of concern I am keeping track of (I am planning to ride 8/1 - 8/13): the Canyon Fire and Shady Fire. Would love to hear from anyone local if the smoke is bad in the area.
Not sure about your other questions, @uncabuddha, RE: snow on the pass and hammock sleeping

Would definitely have some method to hang your foodstuffs from bears -- I bring a long cord to hang a bike bag or drybag of food and toiletries.
I'd be curious also to know if anyone has intel on washouts along the route.
Thanks!
