Great advice above! I will second the eyesight thing, as Iowa whitetail hunters I think we worry too much about their nose. I don't worry about that much anymore. Eyesight is first, you will be shocked at how far they will bust you from. As you are driving to your hunt area from Iowa stop and look at almost every buck you see with binos and spotter. I saw a lot last week driving home from CO. After you look at 20+ bucks you will start to see what a small, average and bigger buck look like. In my opinion that's all a "first 5 years" antelope hunter needs to know. Don't get hung up on he has to be 15" tall or X amount of inches Bonne and Crocket. If you like him, that's all that matters. If you have doe tags be sure of your target and make sure the animal doesn't have a black cheek patch = young buck. Take leather gloves and knee pads, and a butt pad if you plan to sit and observe for a while=cactus everywhere! and Ditto on OnX maps chip in your GPS, I can't even imagine hunting without one. Also get out of the truck and go look into all the small sections of public land that you can't see all of from the road. Have coolers of frozen milk jugs in the truck at all times, bone the meat out where he falls, and get it on ice ASAP and it will be delicious. If you want a shoulder mount beware that their hair falls out easily and you can't drag them around like a whitetail. Have fun! I'm super jealous!
