I've never hunted any of those huge tracts of managed ground but I can tell you that 300 random acres in Kansas, Iowa, Missouri, etc. is still exponentially easier to hunt than most of the ground in MN and presumably MI and other high pressure states. Your average MN fawn in November has seen more hunting pressure and is smarter than the average 4 year old buck in those states, and I've hunted most of them. That is not an exaggeration. I have had MN fawns pick me off out of good, high stands with cover at 100 yards and had 140" Iowa bucks stare at me 15' up a virtual telephone pole at 20 yards and then keep coming. If you can kill any deer with a bow consistently in a high pressure state you are good enough to kill mature bucks anywhere in the good states.
On a side note, a couple years ago Tiff was complaining on one of her shows that it was the middle of November and her and Lee had yet to shoot a buck. "We've worked SO hard!" she said, I thought, "bitch, you've been hunting, not working". I get it, you're trying to put a show together and this is what you get paid to do, but hunting for a living is not the same as wrenching. And going 30 days without shooting a wall hanger is pretty common for most of us. I like Lee and Tiff and they are good at what they do, just pointing out the disconnect between TV hunters, huge managed ground - and the rest of us.
