Each story like this alters my own kit. After decades of knowing how valuable a whistle can be I finally ordered a pair of Fox Micro's a few days ago. blush And I still don't have a proper mirror. But of course, got the sexy stuff- knives, mylar sleeping bags, ferro rods, Chitosan-based hemostatics...Now before you bash me too much, I am back-filling the mundane stuff a little at a time.

I do at least carry GPS most of the time.
