"That video is worthless? Really?"
No, I said worth less, not worthless : ) And there are some good ideas in both videos I have filed away in my memory bank, thanks.
A lot of times when I build a fire in marginal conditions, I can get it to burn for a while, but then it sort of fizzles out. You need an hour and at least 10 times as much wood before you really know you've got it going.
If a fire is big enough, like a bonfire, it won't make any difference if it's raining.
And if it's raining hard, there's no way you'll dry out as fast as new water is getting you wet.
If you can find a sheltered spot, like under a tarp, but not melt the tarp from the fire, then you could make a fire and get warm and dry. A tree maybe, but after a while most trees start dripping.
So much easier to wear as little as possible that gets wet, set up your tent, take off wet jacket and put on dry clothing and get into dry sleeping bag.
