Completed this trail over four days, camping at the base of Horton pass, Little Frazier Lake, and Crater Lake. Weather was beautiful and there were virtually no bugs, with the exception of some bees around Crater Lake. The only real issue was dealing with some smoke on the 23rd. Coming down Little Kettle Creek through the lower switchbacks was extremely over grown with brush and there was almost as many piles of bear crap as there was switchbacks, but we didn't see any.
