It Don't Matter-Horn

Sit start low on the horizontal rail, first move is out right to the horn of the rail. Reach up left hand to the right most crimp on the upper rail, get high feet, and make a slabby move or two to top out and gain the top. The spirit of the route is to use only the right most crimp, and to stay away from the tempting crack up top, stay balanced and go straight up, but it don't matter. Just climb!

When approaching from 20th St, walk to the up the hill and towards the south side. As you scramble around the corner, you'll see the backside of the boulder. Should be obvious as only a few boulders in this area top 10 feet. 

Pads and an attentive spotter. Punting off the slab could be the beginnings of back rehab.
