Bobbylanka:
I agree a driving range and practice putting green would be very useful, and and I have noted the advice about playing in practice mode, however in practice mode either on the green or in game mode not all green speeds are available, this is essential!
There is a practice putting green on the gameclient page
It allows you to set the speed and difficulty of the green.
As to the driveing range, most folks tend to use #1 at Kiawah in practice mode. It is straight, flat, and you can get little to no wind with a couple of restarts.
Hope this helps.
