Doc, what about approaching the farmhouse on the west wide of the river to allow access into the north side of the bridge? Looks like the driveway is right under the edge of the tree-line. I can check the mapping system through work to see if there is an updated image for this location from the last month or two.
Yep, I reckon that might be the option. Photography looks better from the other sided but beggars can't be choosers.
If you have a better image of the area that would very handy...flick it to me by email?
