I will try very soon. Thanks for all the input! I was supposing that, if I did lose it, the highest risk place would be at a Highland Games, but really, how likely is that? If it's as good a fit as I think, it ought to stay on my head pretty snugly. Maybe a big gust of wind, but I'd probably be warned of that by weather conditions immediately preceding, and take measures to protect it.
Of course with things like my snap-on sunglass shades, I'm always losing them...
