There was another 'Frozen' thread on here a few months back. The movie falls right into what Sue basically said, "if you stupid enough to play that game in real life, you get what you ask for."

However, IF stuck alone, it is generally a good rule to have contact with society and if a cell phone doesn't work where you're going then planning to have a PLB makes sense. I own a SPOT2 so it is usually in whatever pack I have with me. I don't ski, but I guess I might have a pack with me or put it in my pocket. I'm not sure.

As to repelling with 550 cord, it can be done. I have done it from 3 stories up. I made a swiss seat out of 550 cord, I used a carabiner and using rock climbing gloves I repelled down using 550 cord. You have to have good control of the rope through the carabiner so it doesn't get away from you and your decent rate is slow, and the swiss seat will leave some pretty bad and unique bruising.

I think all things considered if I was skiing and stranded I'd more likely have the SPOT2 on me than enough 550 cord to repel.
