I remember grass skiing having a period of popularity in the US back in the early 80's. They even had oranized race competitions. One of my racers went up to, I think somewhere in Vermont, to compete in the Eastern Grass Skiing Championships. He was our best racer but had done very little grass skiing, yet he won the competition, so there obviously must be significant technical similarity. Looking at the photos in the provided links the body positions are strikingly similar to modern snow skiing technique. Looks like it could be a lot of fun.
Seems like it fizzled out in the states long ago, haven't heard anything about it for years. I assume it was liability problems, but don't know for sure. If it's popular now in other countries, as indicated in the links, I assume equipment must be available, probably new and improved, and those interested in doing this wouldn't have to settle for some relic from the 80's equipment. Anyone have info on availability of modern grass skiing equipment?
