Instead of starting out on the crack, climb the face directly below the vertical section of the crack. The crux is below any pro, so don't fall until you get up to the crack.
Protection
Friends to 2 1/2" and nuts.
There are also chains on the top of the crack, which can be accessed climbing the wall (5.0) through the trees on the left (street) side of the main wall. Go the the edge, and then follow the fence for thirty feet.
