Not sure if it was mentioned, but a discussion on clothing is warranted. By clothing I mean boots, socks, how to layer, jackets, head wear, ect.
No one needs the latest camo pattern to get a deer, but, if you aren't warm and can't spend quality time in the woods, that hurts your chances.
Cartridge and basic rifle set up might be worth mentioning as well.
