It's the next big thing, it's not Mountain Boarding and it's not quite Skiing. It is Grasski, using specially developed Ski's that can go on grass. You don't need snow, can do it any time of year and with the onset of global warming and less snow on the hills Grasski is more popular than ever.
Checkout the videos below, Grasski offers the same if not better experience than skiing or snowboarding, without the cold and other restrictions that might come with a snow sport. There are even Grasski events and competitions in Europe and the USA happening right now that are getting bigger and more popular every year.
