As a golf professional who stays in one place year round in the northeast, winter is when I play most of my golf. I work a normal person's schedule in the winter, five days a week, 8 hours a day, so I have the time to play and therefore don't really care about the weather. Generally 20 degrees is my limit, if it's not windy. I love playing in the winter, the greens are fast and hard, and my home course plays like it shoud, i.e. you have to consider your approach instead of just flying a ball into the green and expecting it to hold.
