Dirty Rat

Climb the crack a few feet to the right of For Slab Rats Only, with two trees growing out of the crack. It is fun moves, but its rather licheny and dirty.

Parallels For Slab Rats Only on the detached wall you encounter before you reach the main wall at Lower Slabs. The top is the same as For Slab Rats Only, and puts you a few steps away from the start for Discrepancy and neighboring routes.

Standard Seneca rack, but no large stuff needed.
