I snowboarded through high school and most of college for a total of ~6 years. Mostly because most of my friends snowboarded and it's just easier to board with boarders and ski with skiiers (strapping in, typical pace, approach to the mtn, avoiding flats etc). I always preferred skiing though because I grew up rollerblading so it's more natural. Also after getting into backcountry, it's a lot easier not to get stuck on flats.
