Organization: Much like your hunting gear and decoys, you better have things in order. It's tough to try and juggle multiple jobs while in the field, so why make it harder by not having things put together nicely? Have a separate tote or container for cooking, cleaning, and food items. Knowing where things are at can make the difference in seeing the animal and taking a shot, or watching tail feathers fly by.
Preparation: Know about the weather you may encounter, the area you are hunting, and, of course, how many hungry mouths you will need to feed. The more planning and preparation that is done before the trip, the better it will make the entire hunt. Depending on the trip, we will spend more time thinking and preparing the food, than the actual hunt itself. We have eaten lobster breakfast burritos this fall in the blind--all pre-cooked the night before. A simple re-heat in tin foil the next morning in the blind and we were eating well!
