My pleasure. I hope some folks are finding some of the information useful.
As always the "We're all victims of our frame of reference" truism is in play. This is stuff that has worked for me in my applications. I have had very heartfelt disagreements about what constitutes "mission essential gear" with guys who've got just as much, if not more, experience as I do. What's good for guy A might not work very well for guy B.
Sir, I'm sure you're familiar with "The Gift of Fear" and "Blink". Gut feelings can save your bacon for sure... If you're paying attention.
Something I've found very interesting is that my fiances 5 year old son can pick out people who don't look "right" almost as well as I can when he and I have sat and watched people. He knows what a relaxed human being looks like and he can tell when someone isn't. It was amazing to watch how willing he was to trust his gut where adults might second guess themselves.
