Well good evening Mr. Mainer and welcome to the sight. I'm from Western NY and I love to hunt swamps. I'm not familiar with the woods of Maine at all. I could try to help you out a little bit. If possible do you know if there are beaver dams and small hidden islands full of thick pine and cattail, also dry strips running through the swamp. If you have any of these it usually makes for good pinches/funnels. I almost always find what I call a "swamp buck" within areas like this. An old, solid, mature, wise deer loves to use the swamp as his area because a predator will rarely venture into a swamp. I hope that this helped you out a little bit. It sounds like your approach (pre-light setup, scent control, etc.) is excellent. I tried through 3 different recruiters to be a Marine after high school but my 2 knee ops. denied me. Semper Fi.
