 Because grass fires are essentially open to the full force of the wind, they can respond very quickly to changes in the wind, but also the gusts in the wind, so it can go from a very quiescent fire to a really raging fire in a matter of seconds. If you were caught in a grass fire, there's no other option but to seek shelter because you could not run through the flames and hope to survive. There's no questioning the facts.
