Assuming you are in an area that accepts scores in the winter for handicap purposes, what happens to your handicap in the winter? Mine goes up usually by about 4 points--almost doubling. Why does yours change? Courses play tougher because the grass is more dormant, the ground is harder and the ball rolls out, chipping and pitching gets harder, etc.? Or is it the weather--wind, cold, etc.? Or is it the equipment--balls feel like rocks, need different clubs but don't change, etc? Or is it your stiff, sore body? Or is it all the above? Or what else?
