Thats a crazy video! I think its easy to look back at other people's mistakes and say that we wouldn't have made them.There are definitely decisions that I've made, that I would do differently in retrospect. That being said, this is pretty bad, with LOTS of reasons to call that line off right now: recent significant loading, underlying snow strength, observed avalanches everywhere, consistently shallow snowpack in that area, and the consequences of a slide in that type of terrain to name a few.
But, I'm coming to the conclusion that the airbag pack is becoming a piece of equipment like the beacon: something that does not affect our decision making as far as terrain selection, but is there as another emergency tool if one incorrectly evaluates conditions and a slide occurs.
