Kristen,
I hunt in Arkansas, so we' re neighbors. I know what kind of cold you' re talking about (although I cant say we' ve had a really cold season here in the last few years). But when we do get a front coming down from up north it can get DANG cold and its made all the worse by us not being conditioned for it (let one of those northern Yankees come down here in August and see if they can make it through a two-a-day football practice like our boys do, then they' ll understand what cold is like for us). Here' s my advice....the price you have to pay for really good cold weather boots and gloves is worth every penny. I keep a pair in the truck at all times in case we get a cold snap. If you can keep your feet and hands comfortable and dress in layers everywhere else you should be fine...if you can make it until 10 AM or so you should be in good shape...usually warms up pretty good after that most days.
Good luck!
