We Bowhunt Ill., Iowa & Wis. almost every year& 95% Public access. I have a 160 class Bucks being missed on video in Ws. last year 1 in Iowa & 1 in Ill.. Several others seen but out of Bow range.
Ws. is over the counter for tags-Ill. & Iowa have draw or quota.
Bowhunting North America Videos (web page) 1-563-243-7877 has a video/map informational package for under $30 about public access in all 3 states. Some places they cover are managed for TROPHY bucks.

Deerslayer_37 Just a comment, if you own 640 acres why are you pushing the public land and keeping " all the bucks on your side" Iguess that didnt sound right, to me it sounded like you want to hog ALL the deer. 640 is alot of land, ISEN' T that enough? Can others try to enjoy themselves while hunting on the public land without hunters Driving the deer and " hogging them" . NO offense, It probably just came out wrong, but thats what it sounds like. Good luck hunting!

Buy the way what area of Iowa do you hunt?

I' ve quite alot of big bucks on public land in Ohio the southeren to mid part of it mostly.

Ohio, Lots of public land south and east with shotgun\muzzleloader firearms season. Plenty of deer get to grow big. Scouting for turkey yesterday on public land and found several forearm to calf sized trees rubbed up. New spot!
