yeah I have a snowskate and you wouldn't believe how much fun me and my friends have with this thing, we can us it just about anywhere there is snow; but we have the most fun sliding down the little hills that the plows make all over town.
wee also use pieces of wood as rails and slide arround on them (dangerous stuff, I almost broke a rib falling on one, worst pain I've ever felt). Anyway it's great fun. We can even use it on a trampoline!!(might not try it again though, I busted my balls last time
)
Have you checked Kazaa? there's a couple of videos on snowskates.
Oh and I don't know if this is really important but my snowskate's brand is Premier....one of their first models I believe.
