Did this a few time on a top rope. I would not suggest placing gear on lead as there is lots of moss/fungus on the rocks and many of the rocks are lose. I did a few sections and feel the rating to be between 5.6/5.7. Fun little climb, easy to set up a TR at the top.
walked back down the A.T. to come up the face. I didn't have my climbing gear or rope, so I hung close to the right side where it is not quite as steep, but you still don't want to fall there, could really hurt!
