Dont get bummed out,its still early in your season. Our season here in MS is over and the birds are just now acting right where I hunt. Just the way it goes, me and my best friend are going to take our 2yr olds out and try to have some fun calling in some hot birds. Should be fun.
Give it time and dont give up it will happen. I hunt every morning after i get off of work. I loose a lot of sleep but i also get to scout out a lot of new land. (I also just love being out in the woods) My father in law Zeroed this year, he was on birds every morning but the place they were in was open and he's hunting some old birds. It was the first time in 38yrs that he hasn't taken a bird. He's not in the best mood about it, but its hunting and he'll be back in there next March.
My dad hunted a bird last year for the entire season and got him on the last day.
If you find a bird or you know where one is at try hunting him in the afternoon after school. Try and get him before he goes back to roost.(its not the most fun but it works)
A strut zone can be in a number of different places. The best place to find them is on old road beds in the sandy areas. You will see tracks and wing marks (looks like scratches in the sand) Other places will be on either ridge tops or bottoms where ever he can see and be seen. Those are harder to find. Just depends on your terrain.
Just be patient and dont give up. Remember to just have fun with it and enjoy the outdoors.
