On this pilgrimmage to Colorado, I will set up a private lesson. I ride lift-assist backcountry for the most part, with occasional snowshoe expeditions. I've taught.
I think everyone can benefit but I'll post results of my lesson(s) in March when I return.
Skiers take lessons their entire lives. They also improve, even though they may physically decline. That's a lesson in and of itself. I've never skied but I'm not too proud to observe.
I hope to work on better tree riding and better/deeper carving. Hopefully it will pay off. The PSIA/AASI guys I've seen work are good...really good. I want to get better so I can go further/deeper.
Practicing poor technique just makes you better at poor technique. Business has taught me that.
