Theres no such thing as too cold.

I hunted in -7 degree temperatures last year.

When I went to get down after hunting all morning, my glove had frozen to the grip of my bow.

I spit and it hit the platform of my stand. Before it could drip down to the ground below, it froze solid.

If I've got a tag in my pocket, I'm going to be in the woods at every opportunity.
