There are so many ways to enjoy the snow. Free skating is like skate skiing, but you don't use poles to propel you along. You push off with the edge of your skis to give you momentum forward and your arms swing to assist the motion. Check out the video to see what it looks like. It's really graceful.
If you love ice skating or snow boarding because they don't require poles, you may prefer this Winter sport over free skating or cross country skiing. Once you get the technique of balancing, pushing off with your skis, and swinging your arms, you'll be able to move quickly on flat surfaces. Also, it's incredible exercise for your lower body and really fun to try since it takes so much coordination and balance to get going. If you're interested in trying it out, call up your local ski resort or outdoor center and see about renting equipment and taking a lesson.
