Agreed Hikermor. When travelling by foot, the likelyhood of losing your pack is low as long as your common sense is at least medium.

Air travel makes me shiver for just that reason, actually. Even a trip in the car could find you seperated from your gear. It's something I'm thinking about as I prepare to swith my daily commute from car to a combo of bike and train.

Best to just make a habit of carrying your bare essentials on your person.
