Really last week was off the cuff, and was generally a "What are you doing to prepare?"
How about, "Are you
really prepared?" While conducting a net one day many years ago from his home, a ham (not me but someone else) really,
really embarassed himself when he went off the air. The reason? A $.45 fuse failed! And he wasn't able to fix it right away: he didn't have the backup fuse!
It's always the small stuff that knocks you off the air.
You may wish to segue into a wider discussion, subject: Problems occur when something goes wrong. SHTF occurs when SEVERAL things go wrong, in sequence. A great example is that of a ARFCOM member who posted a few months ago about his "afternoon" 4x4 trip that went seriously wrong. First he got into snow he couldn't get out of. Then he didn't have his own recovery equipment: he'd left it at home. Then, he couldn't get a cell phone signal.
THEN ... it just kept cascading. Of course, he wasn't prepared for an overnight stay: no heavy jacket, let alone sleeping bag, water, food, etc.
Disasters occur when a CASCADING series of failures occur. Good subject for discussion, I think.
