I've seen too many good bucks bed in the swamp. I wouldn't go through the swamp, I'd setup on either side of the swamp between the swamp and the food source. I'd look to the woods as a staging area between the swamp and the food source. Seems like you've just about figured this out. Don't spend too much time in there scouting, start figuring which trees you want to setup in and stay out till the season opens. Some of it you'll figure out when you're hunting and you see what is coming from where. Sounds like a great place. Good luck!!!
