I have a snowboarder friend that does this, and I HATE IT. I'm eternally worried that she's not going to hear something coming up behind her, or (god forbid) some out of control clown in the terrain park. I can understand taht under certain circumstances it wouldn't be a big deal, but she has it loud enough that she can't hear me talking next to her on the chair. But I'm not her father. What can I do? I just think that it adds an unnecessary amount of danger to what can be a dangerous sport.
And please no comments about snowboarders. That has nothing to do with it.
