How often do you check your nuts?

[Silk]

Ok, serious question here. I love my car, but there's sometimes less of it for me to admire as it tends to revert to its component form on a regular basis. How often do you do a once-over of your nuts & bolts to make sure that no critical or decorative element is about to separate from the mother ship? Relatedly, do you recommend liberal use of blue Locktite?

And just out of curiosity, what's your best story on significant parts loss while in transit?? Inquiring minds need to know.
