RE: AIRIAL PHOTO
I' ve been meaning to post an aerial and ask the same question.
Looking at the aerial I guess I would look into the spot on the bottom (south?) end of the pond. Especially if you can get a shot at the pond and the clearing from the power line. They don' t look to be too far away. That' s where I would check out.
Good luck. I wish I had a big piece of woods like that to hunt.
