DEFIANTLY move the blind OUT of the hole, no matter how you brush it, it will stick out like a sore thumb. Put it in the edge of the standing corn and make it level or lower than the profile of the corn. Even if that means not having a floor and just standing in the water. Just make a normal blind without a floor thats low enough to not stick out over the corn. Its just as comfortable, you just gotta stand in knee deep water. Or go the extra mile and make a water tight blind that goes under the water. If you have the equipment, using an old gas barrel for a bind works awesome. I can pm you some pics if you want.
It's not a passion it's an obsession
