The thing about a rope is someone has to be there to throw it to you, most of the people that perish going through the ice are alone... or the people that are with them go through too.Ropes and ice pics are second and third on the safety list...
We were out on the ice and we brought a rope with us. not very often do I or we carry one. The one thing that bothered me was that out of 5 guys on crap thin sinking ice was that I was the only one that was carrying spikes around my neck. I think those are as important if not more important then a rope.
