We had a discussion about this awhile ago, and, as Kneale said, trails ratings are relative to the area you sre skiing in. Some resorts have been accused of rating trails as Green that should be rated Blue, simply to sell real estate on that side of the mountain.
That being said, from east to west, there are some vast differences. The obvious one, as I mentioned before, is powder. No matter how much of a "powder dump" we have ever gotten in the east, including Jay, nothing compares with Fernie.
The second difference is size, and depending on your endurance, size matters!
Most trails out west are longer than east coats trails.
Of course, as in the east, there will be some variance within different resorts in the west. At Sunshine, a blue trail is of the same level of difficulty as an NE blue. In some ways easier, since everything is so wide. My husband skied one black that was not overly challenging.
So now that we have you completely confused, whan are ya'going? [img]smile.gif[/img]
