think speed also--that's what the survival kit we are carrying is all about--kit??remember those??--matches,fire starter,candy bar--
i would think that in a real survival situation that looking around for some exotic fire tinder in a wet world,you would not need tinder in a dry one,that hypothermia would catch up with you before you found enough mouse nest and plant fuzz to get a big fire going.but having said that knowing what to look for and giving it a try before had will save time and you will need ever minute.
