One last tidbit of info before I start my honey-do's. Friends of mine always told me that it was next to impossible to get permission to hunt private land around Iowa. When I got stationed here to finish out my 30 year military career, I started driving into the country and watching for deer. When I saw large groups, I would drive up to the farmhouse and request permission to hunt. I was frequently told "No", and I would then politely thank them anyway. I always used "Sir/Ma'am" when speaking to the landowner. Many times after being denied, and then thanking them and wishing them a nice day, the farmer would change his mind on the spot due to the POLITENESS.
Another thing that has happened a lot is I made it a habit to eat lunch in small town diners while hunting. Local farmers seeing me dressed in camoflauge have approached me during lunch and requested that I hunt their property to get rid of deer. Now that I have 300 acres of land to hunt, I ask these farmers for their name and number and tell them I'll get one of my friends to help them out. I then turn the name and number over to a friend that I know will respect the farmers property and livestock.
Now, all those friends who told me you can't get permission have land to hunt on and I have mine. All it took was basic civility and politeness.

Good luck to all.
