Iowa Resident been chasing whitetails with bow for 25 years in West Central Iowa- Carroll and Guthrie Counties.
I disagree with the previous statement about coming here from 11/8-11/15, especially for a bucket list hunt. In this part of the state in my experience you will be fighting lock down and seeing very few mature bucks. Depending on the weather, the does may have the big boys out of home areas and out of the woods making them even more difficult to locate. During this time you can be just as likely to jump one on a fence row or out of switch grass as having him walk by your stand. They can be very dispersed at this time unless we get several days of cold weather or ideally some snow to get the does to hole up in the woods and heavier cover. My trail cameras have proven this behavior for the last several years. I have the same mature bucks on camera regulary until about 10/29 or 10/30 and then they become far less frequent visitors as rubs and scrapes are abandoned for seeking/chasing.
I much prefer the last week of October and the first week of November for patterning and calling mature bucks as they transition from fall pastures to pre-rut and eventually peak rut (usually landing around 11/7 or 11/8). During the peak and peak breeding you may see a lot of deer, but they are far less predictable and less likely to respond to rattle/grunt/bleat. I have taken all of my biggest archery bucks during two periods from 10/25-11/7 and then from 11/20-11/30.
As far as where to hunt, here is a link to the real time harvest report.

Begin your search by selecting counties with the highest harvest numbers as this generally indicates counties with the largest populations of deer. Northeast and Southeast Iowa are the perennial powerhouses, but there are several counties in the southern two tiers of counties with good deer hunting as well as some of the counties bordering the Missouri River. That being said, don't overlook some of the central Iowa counties that are in the Des Moines, South Raccoon, Middle Raccon, North Raccoon, and Skunk river basins. There are farm fields adjacent to these river valleys, and they're sprinkled with timbers and wood lots that provide cover and means of escape during the gun seasons.
After you've narrowed to the top 10 list of counties, go to the public hunting atlas to identify places in those counties with access. Here is a link to the atlas:

Best of luck to you!
