Indeed re ignition, but respectfully *disagree* re result. I remember reading that one of the reasons that (eg) California wildfires are so destructive is that controlled burn-offs are prohibited by law, so there's much more dry material around ready to go *whoomph* at the drop of a lightning strike.

.... Apologies to one and all (here and in other threads) for flying off the (scythe) handle so much today. Please put it down to post-cruise dischuff with the state of the world, and not having done controlled burn-offs for a fortnight.
