Maybe I'm missing something but I will never understand how tee and/or tee marker alignment can be blamed for golfer alignment issues. Stand behind the ball, pick a line, and hit it for chrissake. Obviously, blind tee shots are another matter. Not saying that an effort shouldn't be made to make sure tee markers are properly set but c'mon. Do you need a caddy carrying a set of tee markers so you can set up for your approach shots too?
