Yep, I agree that the fight-back is an option and there's no point doing so with a twister or earthquake. People though, I guess I'll choose nature over them most of the time. My cat for instance, she's better than most people I know. Lol.
As for bears, I have read about the food storage thing and it makes sense. In my head though, I have bear attack images from the move, The Revenant. Great movie. Koala bears don't attack like that.
