I have a farm in Davis County, although not terribly close to the Pulaski area. It is true that deer numbers are down across this area of the state compared to what we had, BUT...there is still good hunting and in southern Iowa in November...anything can happen.
From what I can tell, the deer population is very situational depending upon neighborhood. Not all areas are down, but some certainly are. I drive through some areas now where we don't see very many and other areas are like they used to be and you have to really keep your eyes peeled while driving.
The EHD impact was spotty...we never found a deer on our place that we think died from EHD, but I know others only a mile or two away that found many casualties, particularly in 2012.
Also, the other main factor that has reduced the population is the aggressive antlerless harvest over the past 5-8 years. But again, this is spotty, because some areas were essentially over-harvested and others weren't. My guess is that you will have a pretty good chance at a nice buck, but maybe not as good as it was 4 or 5 years ago and back.
