Start in the back of the roof on jugs and climb out the right-facing rail feature. At the big opposing jugs (where the line intersects a perpendicular crack), either continue straight out to the fin and a big move to top out or cut right past a small pocket and opposing undercling. This is a great problem to play around on.
Location
Around the middle of the Bat Roof, look for the obvious right-facing rail feature. Starts in back of the roof and goes straight out.
For extra pumpage, start on this problem and traverse the jugs all the way left to top out six feet right of the bat cave problem. Easy but very pumpy!
