I recall hearing rumors in the past that at some resorts in the 70s they wouldn'tlet folks get on lifts to the back bowls and really steep terrain if they had skis shorter than 180 cm. Also, I heard there were areas where kids under 18 had to earn patches to wear on their jackets before they could take lifts to harder terrain. I'm not sure how practrical that would be in the modern world.
Didn't Mary Jane do this on Outhouse and/or Drunken Frenchman? I had totally forgotten about that. I was on 180s as a 12 year old, though (okay, that cracks me up), so I never worried about it. But my friends were shorter than I. Why are the memories so fuzzy? darn
