RE: Too Hunt or not Too hunt?!
I like your set-up. Years ago we had I-75 to our backs, with a field in front of us and a bedding area of thickets and pines to our left.
After lunch, I set my buddy up in a tree stand 40 yards off of the Expressway, facing the field. I thought the deer would use the woods besides the Interstate, instead of running through the field. I slowly "bumped" the thickets and sure enough a big 10 pointer came sneaking through with his head down and my buddy thumped him ...
If you get a good hit on the buck you're after, he won't get too far in the swamp, if it's as deep as you say, as he will be exerting more energy trying to escape in deep water as compared to shallow water ... Good Luck!
