I would locate deer travel lanes (trails) leading to and from feeding and beddeing areas. If your property has a thicket in or near the bog, I'd hang a stand 15 -25 foot high overlooking the trails or where two trails intersect. It sounds like the deer are going to be presured and nocturnal when you get to hunt, so setting your stand or stands on trail edges of bedding thickets or on trails leading into feeding areas would be a good idea. I've noticed once the deer go nocturnal, they try to be in bedding areas before first light. Setting up over looking a trail leading into your thickets or bog might get you a deer coming in a little late one morning. As Mb says if there is a dry island in the middle of the bog and you can wade or boat to the island an hour before daylight, you might be in a big bucks bed when he gets home at twilight, set up a climbing or a ground blind and be waiting.

yup the bog get as high as u can with hang on stand and sneak hunt in in the morning deer should hold pretty tight to where they are and even get up and walk right by u. they know the swamp is hard to get into and thats why they go there. you shouldn't worry about bumping deer if you are just get in there supper early like 4;30. the last days i usually sneak hunt the whole day just walk deer trails slow and try to play the wind well ive walked within 10 feet of a deer in a field b4 or it jumped up they will hide until you step on them also get at there level and kneel and crouch through thicker areas and look for movement. pack lunches the longer you are willing to sit the more the deer will identify the area as safe for lack of movement.
