Huffy, I asked my farmer friend about hardpan. He said that's probably why the other farmers places I hunt on don't like me or others driving on their fields when wet. I asked him what he thought about it. He said they plow their corn stubble deep enough that he's never been concerned about a pickup truck causing hardpan or shallow ruts. I'm headed to the stubble again this evening to set up my snows. Thanks for all the replies...
