The air bag at Crystal is confusing to me as well. I find it funny that the same company owns Crystal, Stevens, and Snoqualmie, and chooses to put the airbag at the most non-freestyle oriented mountain. Especially since Stevens or Snoqualmie would be much better suited for it.
Same ownership group for all three, but only Crystal and Snoqualmie have the same management company. When Stevens was sold they stayed with the previous management company, which is why we haven't seen a unified pass yet.
