I'm still a hopeless beginner, but I managed to only land on my butt once the whole day. A couple of the runs actually felt good, rather than just like something that I somehow survived.
Oh, and I did it on my own skis. "My skis" is a phrase that I never thought I'd say, but end-of-season closeout sales were just too good to pass up. If I only ski three times on them, I break even on the rental costs.
