That's awesome you get to bow hunt with your dad and grandpa. Don't get discouraged because the big bucks aren't showing up, they are called "king of woods" for reason. The more time you spend in the woods the more your odds increase of getting to see that big buck. Maybe try waiting until you get a wind blowing into that swamp and use your favorite scent to try and lure a buck out... I will be in WI Oct. 29-Nov. 4 bow hunting in Lakewood on my Grandpa's farm... Good luck this season!
