>>1249007> Do I let my fire burn to coals before sleeping or stoke it up?If you need the heat make a heat reflector and add fuel (or build a log feeder). If you don't need the heat from fire (most cases I guess) put it out and make a new one in the morning
> If I prepare food over a fire how far should it be from my tent?If you have small campfire just for making a meal few steps away should be enough. I like to keep my fire at least 2m away from my tent. Bigger campfires need more distance so the sparks won't burn your tent etc.
