Start in the middle of the roof on top of the large boulder. A direct start from the ground is viable but friable holds make it less than idea. Climb up the face to the roof and then start traversing on monster holds. After the third perma look for a hand swallowing pocket jug in the roof and pull some fun thugish moves on big hold over the lip
Starting in the dihedral on the far left side of the slab is also a possibility. It's definitely easier but adds about 40ft of traverse moves, which can be a welcome warm-up before pulling the crux sequence at the lip to exit. The only downside is that this line gets super wet after a healthy rain. Give it a long while to dry out or you'll be in for a sloppy, muddy adventure.
