Biglake--I can't explain it. The main reason the bucks move in daylight in Iowa has to be pressure (1)... but there are hunters so it has to be more to the story. Personally I think it is the buck to doe ratio is very close, which creates competition for does/food/territory etc... This is why I would like to see APR, it will increase the number of bucks on the property, it doesn't have to be big bucks, more bucks period will make a difference.
It's rare when we get a buck over 150 inches in MN on camera, especially during the day.
Ottertail County looks identical to Warren County, Iowa where I hunt. With the exception of many more lakes in Ottertail and more wetlands/swamps in Ottertail. Rolling hills/hardwood draws/crop fields/CRP/River bottoms. It's the same. Sure the winters are more difficult up here, and the soil is not as fertile, but we still should have good numbers of deer and plenty of nice bucks up this way. I think we all know what the real difference makers!
