I recently tride splitboarding in the woods of VT and I have to say that I'm hooked. I revently became a member of the split site after meeting a group of splitters and trying it out. I look forward to getting into the scene and eventually travelling out west to hit some backcountry in Tahoe or Utah.
I am leaving for Utah later this month and I think I will try a split out there to get the authentic feel of high altitude backcountry.
Voile makes a DIY kit for a split, I saw a small article on how to make your own in a recent issue of snowboarder mag.
Until I find that I have a real need for a split, I'll hike or shoe with my neversummer though, its a big bullet to swallow when talking of buying a split on the east coast because of the snow compostion and short season, and most of all, the time I wish I spent riding instead of working.
