So, hopefully, this is the correct route, anybody feel free to correct me if I am wrong.  The guidebook shows three routes to the left of Poposer Cowboy past the big rotten crack system with Salsa for the Sole being the first of these three routes.  I looked and didn't see any route between this one and Poposer Cowboy, so I think what I am describing is Salsa for the Sole, but the photo in the guidebook for that route looks further right of what I am describing, hence my confusion.  This route starts up an easy pocketed slab (a bit dirty with lots of sand in the pockets) until you get to a bulge where the real climbing starts.  Surmount this bulge using some shallow 1 1/2 or 2 finger pockets to a nice clipping pocket below the steep headwall with a crack through it.  The crux is getting through this crack, but don't expect crack climbing skills to help you too much.  From the good pocket reach high to a sidepull/pinch/crimp then pull through to a chockstone in the crack that  you can use to clip the next bolt.  From there, The crack heads left, gets wider, and the difficulty eases up significantly to the anchors.  

From Zorro, head left passing Poposer Cowboy, then walk up the steeper trail and this is the next route to the left of Poposer Cowboy.
