I've heard the same thing. Can't find nothing about it in the rulebook. I'm 15ft up in a shooting house looking over mine right now. It's on a slope so I can see through it. If I thought it would get more deer in here in the daylight, I'd sure bushhog some. I wish I could see as many as 257 sais he does. He is apparently in a place with pretty good density. I'd just like to see 20 deer in a field once. The best we do is 6 to 8. That's rare. Don't think standing corn is a magic wand of some kind. You can't see big numbers if you don't have big numbers.
