I lived most of my life in Illinois and probably hunted deer for 30 years or so there and considered myself a pretty good deer hunter there. I started out with a smooth bore shotgun and then went to a muzzle loader when they allowed that and then went back to a riffled barrel
Rem. shotgun with a 4 power scope. About fifteen years ago I took a position with the Missouri parks system and started hunting in the Ozarks. Boy, talk about a difference. I started hunting on my father in laws land and from it to the next road was 6 miles and it was all hills and trees. My Illinois skills were not worth a lot here and I had to learn all over again it seems. I am finally getting to where I can do a decent job again but for a few years instead of venison I ate chicken.
Good luck on your hunt in Illinois.
