One problem with that hour glass shape in the center is there is about 100 yards of open field between the points of them. This is why I think it would be a better setup with corn bordering the center funnel. Also, it is basically a "hedgerow" along the creek to the south leading to the funnel from the west.

I know bucks use it as there were some nice scrapes over there.

What else this map doesn't really show you is everything to the NE and Sof the area circled in black has very large hills, I am talking some BIG hills.... Although this river bottom is flat as a pancake....

Germ,

I do not own a john boat but have access to one. My problem would be getting the boat to and from the water with me as I could not leave it there.
