This is a good time of the year to get some cold climate range time in. We often hone our skills in a temperate building but that may not help you may find yourself out in Minnesota's brutal cold. If you can find an outdoor range or somewhere outside of city limits where you know its safe to practice then have at it.
Let yourself get a cold including your hands. This obviously will affect your accuracy but it should help you learn to keep control so you can place decent shots. The brain is powerful and can adapt to just about anything you throw at it. We often underestimate the minds power to overcome many obstacles.
"What country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms." -Thomas Jefferson
