Where I hunt it doesn't have too bad of an effect, yes the deer change patterns but I do the same and it all seems to work out. Most gun hunters that are around me hunt open areas, the deer will skirt those areas and stay in the thickets, which is where I hunt anyway... Our archery season starts Sept. 26th and the general firearm season starts normally the first weekend in November and runs till the end of the year, then the first two weeks of the year there is a doe and spike season open in our county.
