I've never crawled up on the shore out of 33 degree water & tried a fire. But have practiced after ice storms & such. All here are correct in saying every one should practice with what they choose. Some choices can be eye opening.
And another thought... certain tools & gadgets should be on your person. Not in a pack that's in the boat or vehicle. Those supplies are useless when the pack is is gone for 1 reason or another. If certain important things aren't on your person they should just as well be left at the house.
