This isn't Fallout-related, and it's barely related to gaming at all - a golfer in Irvine, CA, sets fire to the course when his club strikes a rock on a swing, and makes a spark. The blaze attracted 150 firefighters to extinguish it. Most of the course was unscathed, but some rough was burned before the fire spread away from the course to char two nearby hillsides.

I can't remember the last time a videogame started a wildfire... :P
