Once you're in Wall St. Bowl, the obvious way down is to follow the bowl's drainage to the right, and down, since the fall line is a huge row of cliffs.  However, in this case your instincts are not correct, because the drainage is a tight narrow chute, about 45 degrees steep, with a tree to limbo under on your way down. It turns out if you head straight down, over the cliffs, you'll find a secret ramp for an easier exit (see the next picture).
