RE: I need some advice
you will find the biggest deer on the most unusual places. I've ran out HUGE bucks out of very small draws with one or two trees and 100 sq feet of tall grass while pheasant hunting.... I've seen deer walking out on the open field heading out for water where there are no trees within hundreds of yards. I've seen deer swimming at a private lake while I was fishing...
My point is try to find a good spot, and either climb or sit on the ground real still where you can see most of the area. If you are careful with the wind and move VERY slowly and NOT very often, you can shoot a deer from the ground. My father in law shot a 10 point buck 3 weeks ago from the ground at 15 yards. He was sitting against a large tree next to a trail.
I'd give the swamp a try if you see deer signs leading to it. Big bucks like to stay where noone else goes. That's why they survive long enough to be trophies...
Good Luck
