On the left side of Crimpfest, there is a large flake-roof that forms part of several routes on this part of the wall. Season Opener attacks the central portion of this roof. It is the fourth route from the left and just left of the obvious right-facing flake on Dave's Dilema. Power over the initial bulge on decent holds (11b) and move up on beautiful flakes to engage the thinner and steeper crux (11c). The route then eases off to typical 5.10 Crimpfest climbing, with only a puzzling bulge (that could use more traffic) giving pause.
As with nearly every route on this wall, well worth doing.
