they actually do summer camps down there at Liberty.
Never been, though.
A friend of mine has some Powderpak which we have used a few times now. I think Liberty uses Snoflex (or Snowflex?) essentially the same concept but IDK how they compare.
On the powderpak, at least, edging is different you really can't "carve" or lay an edge like you would on snow. You can kind of side slip though. ALso I remember reading about the dryslope over in the UK and they said the same thing - for instance that you can't really do a setup carve on the kickers or rail approaches.
