What pt of Iowa you from DTK, Im from southeast Iowa. Its gonna be hot here (obviously) and one strategy Ive used is to try to find an area along a creek that the deer have just tore up when drinking water. I did this last year and worked great, usually deer seem to use a certain water hole in the mornings after eating all night and early evenings on their way to food. Ive seen a few during mid-day, but not enough to make hunting the heat worth it. You better believe Im hunting water holes Saturday morning, Friday night Im gonna chance hunting the field and see what happens. I also use ground blinds when its hot, seem to get bit less by the skeeters than sitting in a tree.
