I just wanted to share my experience with a lesson I had last Thursday night at Ski Liberty.  I also don't think there's been a topic on lessons in many years on the site.  I went to Liberty's 5:30 pm lesson (I think Roundtop has the same time and Whitetail at 6:00 pm) and took my chances on a 2 hour group lesson.  Because I was the only Level 6 there, I ended up having an individual lesson for two hours.  The total cost was $117 (I know if I had a night card, it would be less, but still this is a great deal for a two hour lesson which effectively was private plus a lift ticket).  The instructor -- Frank Krach -- was great and taught me some things that I hadn't thought of before.  What a great way to spend a Thursday night!
