I play Nintendo while skiing too
I used to use AstralTunes a long time ago. I also had a BoneFone. Anybody remember those? Most annoying cause they had little speakers
Now I like to hear the wind, chatter of skis, creak of hard snow, or fluff of soft snow, or the laughter of people way across the valley sounding like they are right next to you because of the way sound travels through thin air.
NOW, on the three hour drive up starting at 6am there's some jammin tunes (Punk, Classic Rock, New Wave, Progressive Stuff, i.e...Assorted Genres) played louder and louder the closer I get to the mountains.
This is followed by mellower road trip music on the 3 hour drive home (Floyd for example, but some upbeat stuff too keep me awake)
Not using an IPOD, but using a hard drive MP3 player and 10 CD changer in the truck sound system.
