This is a great time to head indoors and start practicing form and focus. Yardage is big part of 3d, but simply knowing the yardage will not replace great shot execution. We usually spend the cold winter months inside shooting spots and coaching each other on proper form. This is a time when we acknowledge our flaws and spend the time working to overcome them. (yes Ken, I know I still need to get that elbow up, I'm working on it.) We are lucky in our area to have several good shooters and we continually challenge each other to do better.
