Doe: Considering Iowa's present buck to doe ratio and the Iowa deer population and all the tags available for does, I will stick the first mature doe that offers me a good shot. I prefer to harvest does before they are bred because if I harvest one after the rut I may also be harvesting the offspring of a monster buck. But don't get me wrong, I will still harvest a doe after the rut if need be. Also, fewer does during the rut means the bucks have to travel more and look harder to find a doe. Will the bucks leave my hunting ground? Maybe, but most will return to search again.
Buck: Since I live and hunt in the incredible deer woods of Iowa which has outstanding genetics, habitat, and food, I will wait for the first buck that I believe will gross 150" or better before I release an arrow. If you have confidence in your hunting ability the young bucks are easy to pass up.
