Never say never. It's amazing how fast brush and forest fires can move. I've lived through several big ones, so now can't even be around a fireplace or campfire without sneezing. Having a lush well grazed pasture around buildings definitely helps. Looking at topo maps lately for alternate backpacking options. The high country remains lush and is far less susceptible to actual burning, but the smoke from fires further down often siphon up canyons and over high passes, and it's sure a big disappointment to be prematurely chased out of the mountains due to smoke. It can also be potentially dangerous because one generally has to return to lower terrain just to get out, where actual fires might break out. Part of the mantra.
