Personally, no. On the "odds vs. stakes" scale, the likelihood of this for me or my immediate family is nil or even less. I can envision some far-fetched scenarios, but they're WAY far-fetched (use a kidnapping to leverage customer info from our security company, etc). Nothing other than that comes to mind.
We're blue-collar, rural, physically large and armed. No young girls for 'that' kind of kidnapping, and my wife is older (and meaner) than I am. Even my youngest child is the size of a college linebacker, and anyone who kidnaps him
and has to feed him, would soon be paying me to take him back.
Can't hurt to ask, obviously; but I suspect that anyone who frequents this type of forum and has pretty much any real level of that kind of threat, has most likely addressed it already.
