Having spent some time away from the game and this forum, it was good to spend some time reading through this thread. I used to shoot around the 90 mark with the odd lower round and looking back I definitely see a correlation between my scores and finding the fairway\green.
My most recent round was a messy 103 and after reading the many posts I went back through my round and worked out around 20 extra shots due to bad tee shots and iron approaches. The only really bad short shot I can think of was when I was short-sided with a bunker to hit over and ended up on the other side of the green. However that can be attributed to a poor approach beforehand.
So from that I know what my glaring weakness is and will be working hard over the winter to correct it. Daily drills at home to work on it with range session thrown in.
They stand for the mixed tees. Look at the scorecard at the top and you'll see they tell you to play white on this hole, green on this hole, etc. So 7 sets of tees can create 13 specific sets of tees by mixing 1 and 2, 2 and 3, etc.
Well, most courses won't have black tees. And they still suggest, I think, that the tees are numbered or used in some other non-traditional way so that "red" is disassociated with "women's tees" and so on.
I doubt that's true. Some of the tee markers - whether raised up or sunk in the ground - will be in play.
Some drives from further back tees would hit the tee markers in the fairway.
