Came across this awhile back, but figured I'd throw it up here in case nobody has seen it before:
SpyderInteresting to say the least. Think it would be fun to take out for a spin to see how it handles. To me it looks like they basically replaced the skiis and rear tread on a snowmobile with tires. One thing I thought was rather odd was that the tires only require 14 PSI. Thinking that has to be for the fronts only. Can't imagine the rear needing that little air.
