I don't keep my "Golf Log" anymore (see How Much do you spend thread) but I average about 100 rounds a year. I once kept track of the number of days in the year that I did something golf related.....that went out with my log! Here in Michigan I play what we refer to as Winter Golf. When it's too cold in Nov, Dec, Jan, and Feb for the average golfer to be playing (35-40 degrees) we'll play as long as there is no snow on the ground and the course is open. All that is moot when there's snow. The courses are empty, so it's dress appropriately, and play away!
