Never thought of that, but then when I go to a new course, I suck at it again, so I think it goes back to the point of ref. I know the course pretty well at the lake, so I can do it well there, but the ones here, I can never get it right because I only play them once or twice a year. the 150 bush moves every time I get to it so I can never hit the green. Yea, thats it.
