Who wears makeup in the wilderness? Not me!

I do take a mirror--it's one of those cheap camper mirrors (Stansport, I think) cut to 1/4 its original size. Its primary purpose is in case I get something in my eye--in the meantime, I use it for a quick check for smudges on my face. I also use it for tick checks in springtime. I would never try signaling with it. I probably wouldn't need it except that almost all my backpacking is solo (my dog is not much help at that sort of thing).

I've tried using a mirror for signalling with my grandkids, just for fun, and it's really hard to do!
