That is great that arooga and phoenix are thinking of doing it together. Too bad you did not join HPSC this year cause their Instructor training cllasses have already started. For a mere club fee ( 160 early bird) you could have 6 days of ltraining inlcuding ski improvement and teach to teach classes and they are the best preparation you can have for level 1. It is the best value for your money. For younger people teaching is a difficult part. You have to be able to articulate your lesson in a real setting.
Do not forget to put down a friend's name (already an instructor) as someone who introduce you to take the course. His or her name will be entered in a draw for a week of skiing for free in the west! Good luck to you both!
