From my standpoint, Iowa is the easiest state in the country to get free permission to hunt. I highly recommend knocking on some doors first. You are stepping back in time in some of those rural areas. They allocate very few tags to nonresidents so they are not over run. I had a buddy knock on 5 doors in zone 5 and get 5 yesses. He had way more land to hunt than he could cover. One of the farmers ever drove out his stands for him on his ATV.
