the 3 involved had NO avy equipment!!!
That doesn't seem like a very smart decision... if they had the equipment do you think this guy would have lived?
I don't carry a beacon because I don't put myself, or anyone I take out in harm's way.
My theory- plan for the worst so that when it doesn't happen, you can feel better about the day you had. You or your group may not put yourself in harm's way, but someone else in the area might be riding a slope above you and cause a slide... just a thought. Carrying the gear and not needing it is a lot easier than needing it and not having it!
