That's a good idea about picking up tinder. However, for the problem here (snowboarding off piste), I won't be doing that.

I like the idea of the pre-made fat wood. I've never used fat wood. I think I'll buy some to put in a plastic bag in a jacket pocket.

I'm putting together a survival kit that will go around my neck. I'll post a pic when I'm satisfied with the combination of gear.
