This is old, old, old thread.
Anyway, I have been going to the driving range. I don't understand why they keep the drivers line in the back, and everything else in the front. Needless to say, I nearly smacked a few people in the head.
However, one thing that helped is the Wii. Though it isn't realistic, the Super Swing Golf is fun and it sort of helped me keeping the swings straight when I reach the actual driving range. I heard Tiger Woods is much more realistic, so give that one a shot too if you're still having trouble - though I highly doubt the TC is still checking up on this.
