'Cocker,
I assumed the handle refers to those pocket rocket flushers that seem to interest me so much lately (I have an aging setter and am thinking of getting a flusher puppy for the next bird dog), we may need to talk more if you have experience with these dogs.
I live in Linn county (moved here 7 years ago) and unless you are in the best habitat available, you can pretty much forget it east of I-35. Lots of walking for few birds; populations have basically crashed out here. As a case in point, I am in the process of planning a trip to SD or KS to get my "fix". Will also probably hunt NC or NW IA once or twice as well, bird numbers are "stable" there as you are aware. This is supported by the DNR small game distribution map you can download from their website that is based on the annual roadside survey they do. Overlay that over your county maps of public areas and should be on your way.
Now, as far as NC or NW IA public lands, go read the online magazine articles in the "IA Game/Fish" website under "pheasants". Also, check the Iowa Sportsman's Atlas-this set of maps (not the Delorme!) can be bought at most Sporting goods stores in IA and some border states. There is a map listing each county, with the public land colored on each page with a description. Some of the land is Federal or County, and is not necessarily listed on the DNR website, but is still open to public hunting. Most the public lands in these areas of interest will require no-tox shot. Bear that in mind and stock up now, as it can be hard to get sometimes. I really like Remington Wingmaster HD in #6 or Kent Tungsten Matrix #5 loads in 12 GA. I don't have any faith in steel, the expensive stuff really works and it is worth the cost, as far as I am concerned.
I can't be more specific on spots. Those two suggestions will get you what you need. I have done DIY trips to these areas the last 4 years exclusively on public land and done reasonably well. Cattails and frozen marshes will be important areas to target once the weather really sets in; which is a possibility with your timeframe. I would offer you to join me if I was hunting during that time, but more than likely, I will be visiting my relatives back in western PA. (We usually head to my inlaws over Christmas)
Regards,
Joe
