GPS... I just got a Garmin 60cs. I love it. I can't wait to try it snowboarding. Just one of they many uses I think I have found for it. My race car will enjoy hauling it around next year for track maps and velocity plots. I might try to use it next month when I go to skip barber Laguna seca... which would also include altitude

Have you had any problems with getting satellite coverage in a backpack or pocket on a mountain?

I just got a new board last year: Burton Custom with ride MIG bindings and Salomon boots... Spread the wealth. I tried several Burton boards during a demo day and this was by far the best for my style. I would highly recommend a demo day before buying.
