Since NE and MS are both great hunting areas I' d find it hard to laugh at you . Southern Indiana is pretty humid too since we have a huge river flowing through our valley , and it can get rather frosty sometimes . Your prob may be the circulation in your legs and feet , mine get cold easily too . Rubbing your legs occasionally will improve the situation , along with standing up to let the blood flow better . I also keep my feet off of the ground to reduce heat loss .

Are you hunting from the ground or a tree stand ? The wind saps heat very quickly in an exposed stand , which is another reason I love my pop up blind .
