Query: re-discovered sledding with this "real" sled

I've had one for these past 2 winters and just ordered another for my nephews. I think if I had one of these as a kid, I might never have gotten hooked on skiing. I'm finally able to maneuver around obstacles and go fast at the same time!We visited Silverton, Colorado and tried one out at the little ski area there. We were actually able to run a slalom course (while laughing our heads off).I was worried about the heaviness of this thing, but the black bottom slides so smoothly, I haven't had any trouble tugging it up the hills. We picked this one because it is long enough for adults too.Mountain Boy Sledworks Ultimate Flyer 52-Inch Sled
