NUmber one Ski resort

I just read an article in Freeskier magazine about the number one ski resort in North America. The magazine picked Whistler, Blackcomb  which is in British Columbia. They picked it because it has 8,171 acres of ski able terrain. Along with all of this terrain there is skiing for everyone. There are baby terrain parks and large parks. Among all this there will be a tram completed in december that goes from peak to peak breaking many world records. I have only skied there in the summer so i can not say if i would agree with it being number one but from what i have seen and herd i believe that is should deserve a spot in the top 5.
