I wouldn't worry about carrying a pee bottle specially if there is that much water around. Let it go in the swamp.
I would be out of that area, I would rather drive a few hours and hunt good deer numbers, then hunt a place where only 5 have been killed since sept. That's pitiful. You might as well be out fishing. You could be a great deer hunter and come up empty year after year if your hutning where there aren't that many deer.
I also hang my stands only as high as the cover. I've killed 6 bucks off the ground with a bow. Shot this one last weekend off the ground at 35 yards with my shot gun, he never knew I was there.
