Interesting story. Funny how XC skiers like to kick everyone out of every park they use so they can have the trails all to themselves and yet claim to be environmentalists. Then you look at the effort here with helicopters, a groomer, snow machines, housing, etc. Real environmentally friendly and  lowering the carbon footprint of that sport. 

The next time some elitist skier complains about the sound of a snow machine they should ask themselves how noisy this arrangement is.
