If you hunt hard enough and smart enough and do your homework you will kill a nice deer. Hell I went and scouted a cut corn field Sunday morning and watch 6 bucks together 3 of which were over 150. I don't even consider that place one of my go to spots either. If I thought realistically that I wasn't going to kill a nice deer year in and year out I'd do something else. I watch deer all year long. I feel good about my chances. You should to if you live in Iowa. I have had a 150 class deer within range every season for the past 6 or 7 seasons. I didn't kill all of those deer but I had opportunities. That's all a guy can ask for.
