Rich,
Besides what the others have said remember to look where you are going, the board is not going to change colors. If you are going to practice it do it all the way, hands out for balance, shoulders level, look where you will be going soon, all that kind of stuff, not just the movement of your legs.
More advanced:
build a balance board using an old dead board or 2"x8"x36" and attach a 2"x3"x36" board to the bottom of it, making a "T". Mine is an old Hot Blast with a great tune on it. Balance on that in stance, practice the same movements and do squats. This will make your balance much better once you get on hill. You can even add dumbells to the squats for more workout. If you are doing squats you probably don't want to do it with boots on. I don't use boots on mine to help strengthen my ankles.
Hope this helps and the snow flies soon for you,
