Nice picture, but brings back some memories of being caught in a fire with my dad.
He drove like a lunatic to a low dry creek bed, threw my brothers and I out under the truck, saturated a blanket in water and we all huddled under that while the fire passed.
Truck above us shielded us from the heat & wet blanket actually filtered the air for breathing, rather than being in the vehicle that was like an oven. He knew so much being raised in the Australian bush.
I'm now always cautious on the trail from that day on and always carry heaps of water & a mattress protector that is my cargo padding (to saturate) if it looks dicey.
