I can't swear on the bible about this, but I think a lot of golfers do what I do. They don't warm up properly when they get to the course. I am bad for this. I get out of the car, hurry to the first tee, and get that first (usually poor) drive down towards the hole some where. "Oh well, off to bad start again." Second hole is usually not that much better, with the third hole maybe showing some improvement. By the 5th, or 6th hole, as long as I have not let the previous holes ruin the round for me, I am warmed up, and my swing, and putting start falling into place. By the time I get to the back nine, I am on cruise control.
