Sit-start facing right. A relatively large crimp is within arm's reach to the right. Reach back with your left hand for a palm. Once you've stood up immediately reach left for a nice ledge. Walk your feet up, then stretch as far as humanly possible straight up with your left hand for a small crimp. This is the definite crux, but will give you enough time to balance, walk your feet up, and shoot for the lip to top out.
Location
Follow directions to the Radio Tower. Floral Designs faces south and is about 50-60 yards from the road. It's just short of a natural alley.
