I sprained my knee when I was in 5th grade skiing on my parents skis from the late '50s (this happened in the early 90s). I spent 3 hours dragging myself back to the house, freezing cold and crying. Good times.
I skied a little in my teen years and had a lot of fun, got real confident too. I worked at Killington VT for a season after high school. That was a blast. I picked up snowboarding and had a good time.
