I always bring the headtorch when travelling. That and my Swiss Army knife. Partly because I was a Girl Scout for 12 years and trained to be prepared and partly because I had a huge crush on MacGyver and his ability to fix anything with a Swiss Army knife and grey tape.
Space was at a premium on this pack, so the headtorch was left out. Seems ridiculous as it doesn’t take much room, but what’s done is done.
I will never forget it again. This morning the hotel lost power for about an hour. With no lights in the hotel room, I was using the display on my phone to find my way to the toilet.
