I would have to semi circle and come in from the south and use the terrain. Completely not touch that area until I walk straight up the hill into the spot. Sit maybe 40 yards downwind of the water. Tracks tell me they are moving like this....
Knock and ask for access to park and hunt public, you will be surprised how many will allow parking and access, that has led to permisson on their property from my experiences more time then not.
