Hello, again, Penny, A "firebug" is some self-important pyromaniac who goes around when the brush is tinder-dry, humidity is near or in the single digits, and the Santa Anas are blowing. Once in a great while, our brush fires are caused by a spark from a muffler, welding torch, or even from brush clearance that has "backfired,", but the chief cause of fires in our hills is the self-aggrandizing fool who derives some sort of diabolical satisfaction from watching our hills go up in smoke, along with many peoples homes and prize possessions. Are you in Rancho Mirage right now? Ron
