We have a late bow season here in Iowa (dec20-jan10). I waited out early season for a good buck and was disappointed. I have been out every day since the late season began to find a deer to take, but can't seem to have any luck. Temps are expected to be in the 30's with just a tad of snow on the ground. Please help me out. I'm looking for some tips on technique and locations deer may be at this time during the season. Also, does a grunt call prove any effectiveness during this time of the year?
